What's the best way to eat a bag of jelly beans? Many people open the bag and eat all of the candy no matter what flavor each piece has. Others browse the collection. You might say, "I don't like the orange ones." Or maybe they just care about the lemons. There are different types of jelly beans in the mix and people eat whatever they want and get rid of the rest. Demonstrate Aheterogeneous mixtureis a mixture in which the composition is not uniform throughout the mixture. Vegetable soup is a heterogeneous mixture. Each given spoonful of soup contains varying amounts of the different vegetables and other components of the soup. APhaseis any part of a sample that has a uniform composition and properties. By definition, a pure substance or homogeneous mixture consists of a single phase. A heterogeneous mixture consists of two or more phases. When oil and water come together, they don't mix evenly but form two separate layers. Each of the layers is called a phase. In the case of vegetable soup, one phase would be the liquid soup itself. This phase contains vitamins, minerals and other components dissolved in the water. This phase would be homogeneous. Carrots, peas, corn or other vegetables represent other phases of the soup. The different types of vegetables are not evenly mixed in the soup, but distributed randomly. There is a multitude of heterogeneous mixtures around us. The soil consists of a variety of substances and often has different compositions depending on the sample taken. A scoopful may come up with dirt and grass, while the next scoop might contain an earthworm. Smog is another example of a heterogeneous mix. This cloudy accumulation of pollutants can be a mixture of water and contaminants from burning gasoline or plastic, mixed with nitrogen oxide derivatives and ozone. You can see that the distribution of smog in the air, shown below, is not evenly distributed, but varies from one part of the atmosphere to another.

Tap water is also referred to as running water or city water. It is supplied to households by government agencies and standards of supply differ from country to country. It is used for cooking, cleaning, etc.
Tap water is different from fresh water obtained from natural water sources or hand pumps etc. It is obtained by treating water from various sources using various purification techniques.
Deployed mainly in urban and suburban areas, it involves a complex system of collection, storage, purification and supply.
So, is tap water a mixture?Yes, tap water is a mixture. Tap water is made up of minerals (CaCO3, Mg, etc.), microbes (bacteria or other pathogens), detergents (like chlorine) and other contaminants in varying amounts. However, these are only physically mixed, so it is a mixture. These substances are dissolved in water and form a solution in which the composition of different substances remains constant throughout. Therefore, tap water is a homogeneous mixture.
Let's examine it in more detail.
Why is tap water a mixture?
A mixture is formed when two or more substances are only physically mixed together.
There is no chemical association between the mixed substances, i. H. the chemical properties of all substances involved in the formation of the mixture remain the same without losing the original identity of the substance.
The physical properties of the connecting substances also remain the same. However, the physical properties of the mixture may differ from some or all of its components.
The components of a mixture can be easily separated from one another by boiling, distillation, electrolysis, chromatography, etc., by exploiting their physical properties.
Some examples of the mixture are air, ink, crude oil, salt in water, sand and sugar, etc.
Tap water is a mixture because the different substances mixed with water are not chemically combined. Since no chemical bonds are formed, the chemical properties of the water and other substances remain unchanged.
The physical properties of water like boiling point, melting point, etc. can be easily affected due to the impurities and their proportion in the mixture.
It is actually a solution in which various impurities acting as solutes are dissolved in water, which is a solvent here.
Both the solvent and dissolved particles are evenly distributed throughout the mixture.
types of mixtures
Based on their properties, mixtures are divided into two types:
1.A homogeneous mixture: In such mixtures, all the components of the mixture, i.e. elements or compounds, are evenly distributed.
This means that if a certain amount of the mixture is taken from different points of this mixture, the number of different components remains the same, indicating that the properties and combination of different components are identical for the whole mixture.
They only have one visible phase. For example tap water, alloys, brine, etc.
2.heterogeneous mixture: The mixtures where the composition and properties of the mixture differ from one point to another are called heterogeneous mixtures.
The components of such mixtures are unevenly distributed and can easily be distinguished from one another visually.
Some examples are air, crude oil, sand and salt mixtures, etc.
Why is tap water a homogeneous mixture?
In tap water, a number of substances such as minerals, salts or impurities etc. are dissolved in the water. They form a solution with water as the solvent and the impurities as the solutes.
The different molecules are evenly distributed in the solution and cannot be distinguished by their appearance, i. H. they have a visible phase.
However, the chemical as well as physical properties of the constituent particles remain the same.
The properties of tap water, on the other hand, differ from pure water.
Is tap water a pure substance?
Pure substances are the form of matter made up of only one type of atom or molecule.
Hence, elements are considered as pure substances as they consist of only one type of atoms while in compounds the two or more types of atoms are chemically bonded together to form a molecule which is their basic unit and hence compounds are also pure substances.
Pure substances have a uniform composition. For example, aluminum oxide is a compound composed of numerous Al2O3 molecules in which the ratio of aluminum and oxygen atoms remains constant throughout, ie in the ratio 2:3.
In addition, pure compounds have specific chemical and physical properties, regardless of the source from which they were obtained. They require chemical separation processes to separate themselves from the basic components.
Tap water is not a pure substance as it is made up of more than one type of atoms and molecules.
In addition, the properties of tap water can change from one sample to another depending on the percentage of added minerals or impurities present in that particular sample.
This also affects the physical and chemical properties of tap water, which vary depending on the composition and can separate the components from one another by mechanical or thermal (physical) measures.
Tap water vs. distilled water
Tap water is usually obtained from either natural water sources such as rivers or man-made sources such as canals or rain-fed lakes, etc. It is disinfected and cleaned with various chemicals.
After a few processes, the tap water is made usable for household purposes.
However, some undesirable substances are still present in the water, which can make tap water unfit for drinking or human consumption.
You would have heard cases of water intoxication or other water borne diseases like typhoid, cholera etc.
Therefore, tap water is further processed or purified to make it fit for consumption. Three methods are commonly used in various water treatment systems:
• reverse osmosis: In this water is directed against osmotic pressure through a semi-permeable membrane. It removes the impurities and salts but allows the minerals to pass through, resulting in clean water.
• Deionization: It removes the minerals, salts, impurities, etc. from the water.
• Distillation: In this process, water is boiled and the steam obtained is collected in a vessel, which is then cooled and turned back into water.
This removes all minerals, salts, impurities etc. from the water and you have distilled water.
The distilled water is therefore obtained after the purification of tap water using the distillation technique. It is considered good for human consumption as it clearly removes any disease-causing microbes or other contaminants.
However, this process also deprives the water of the vital minerals and salts needed for the active functioning of the human body.
Therefore, consuming distilled water over a long period of time can lead to deficiency diseases.
Below is an interesting video about the reverse osmosis process.
Why does tap water conduct electricity and distilled water doesn't?
Tap water consists of various minerals and salts. When these salts and minerals are dissolved in water, they dissociate into their constituent ions.
These ions are freely mobile entities that carry their own charge, both positive and negative.
To pass electricity through tap water, a positive (cathode) and a negative (anode) electrode are inserted after they have been connected to a charge source.
When the charge is applied by tap water, the ions present begin to respond to the electric field according to their charge.
The positive ions are attracted to the anode while negative ions are attracted to the cathode. Therefore, with the charge movement, the current begins to flow through the tap water.
Distilled water, on the other hand, is free of minerals or salts and therefore contains no ions. Since the ions or charged particles are responsible for the current flow, distilled water does not conduct electricity.
You must also read the article I wrote about whether distilled water conducts electricity.
Characteristics
Water is a colourless, odorless and tasteless liquid. However, the properties of tap water cannot be fully determined as they depend on the various dissolved components.
Nevertheless, the important properties of water are listed in the table below.
Any deviation from these properties is an indicator of contamination, some of which could be hazardous, and such water is considered unfit for human consumption.

Conclusion
• Tap water is a mixture because it contains various minerals, salts and impurities that are not chemically bound.
• It is a homogeneous mixture as the different components are dissolved in water, creating a solution. Therefore, the composition of tap water is uniform throughout.
• Tap water is not a pure substance as it contains more than one type of atoms and molecules that are not chemically bound.
• Distilled water differs from tap water in that it contains no minerals or salts. Therefore, distilled water does not conduct electricity, but tap water is a good conductor of electricity due to the presence of free ions.
• Tap water is used for domestic or household purposes.
