Q2-Things which dissolve are called solutes and the liquid in which they dissolve is called a solvent to form a solution. Strongly polar substances easily attract water molecules. The water molecules surround the charged solute. Water is a good solvent and picks up impurities easily.
Q3-Because some solid are not dissolve in liquid because of the molecules that pack in some solid.
Q5-Some solids change when mixed with water; others do not. Some solids dissolve in water; evaporation leaves the solid behind. Some liquids mix with water; other liquids form a layer above or below water. Observe properties of solid particles in different containers.
VI-Some solids change when mixed with water; others do not. Some solids dissolve in water; evaporation leaves the solid behind. Some liquids mix with water; other liquids form a layer above or below water. Observe properties of solid particles in different containers.
