Answer 2

Categorizing Insoluble or Soluble solution for the following mixtures as follows:

First, defining Both the types of mixtures i.e. Soluble solution and Insoluble solution:

Mixtures are of two major types based on their solubility:

1. Soluble solution: When two substances or solution is mixed and they are physically soluble with each other when one dissolves in the other completely. They are termed soluble solutions.
2. Insoluble solution: When two substances or solution forms a mixture while they do not dissolve with each other completely. They are termed insoluble solutions.

**Based on the definitions we distinguish between the following mixtures:**

1. gasoline in water: Insoluble solution

Gasoline contains hydrocarbon which does not allow it to get dissolved in water and hence the mixture is insoluble.

2. acetone in nail polishes: Soluble solution

Acetone is a chemical present in nail polish removers that removes nail paints from nails. Hence it is a soluble mixture as it can dissolve with nail polish to remove it.

3. salt in alcohol: Insoluble solution

Salt has higher charged molecules as compared to alcohol and hence they are insoluble

4. oil in vinegar: Insoluble solution

Oil and vinegar are two different varieties of liquids, oil is hydrophobic which does dissolves in water and so in vinegar too. They are an insoluble mixture.

5. tawas in the water: Soluble solution

Tawas is a transparent salt crystal of ammonium potassium sulphate which is completely soluble in water.
