Q.7.(C)

Q.7.c. Discuss solubility of solids, liquids and gases in water with the help of examples.

Ans. Solids---  To make lemonade, you take a glass of water. You add sugar, salt and lemon juice to it. You stir it with a spoon and your lemonade is ready. After the lemonade is made, can you see the sugar or salt in it? No. The sugar and salt disappear when you add them to water. In other words, sugar and salt dissolve in water. The substances which disappear or dissolve completely in water are called soluble substances. Some substances such as glass or sand do not dissolve in water. Such substances are known as insoluble substances.

Liquids-- liquids such as vinegar, glycerine and honey also dissolve in water. When two liquids mix with each other or dissolve each other, they are known as miscible liquids. There are other liquids such as oil, petrol and kerosene which do not dissolve in water. They form a layer on the surface of water. The liquids which do not mix with each other are known as immiscible liquids.

Gases—A bottle of cold drink opens with a popping sound accompanied with air bubbles. These bubbles are nothing but carbon dioxide gas. This shows that carbon dioxide dissolves in water. Oxygen too dissolves in water. It is this oxygen that the aquatic animals use for respiration. However, gases like methane do not dissolve in water.
