Answer:
To prepare a true solution of common salt, sugar and alum.
True solution: A solution that has solute particles of size smaller than 1 nm (10-9 metres) in diameter, and cannot be seen with naked eyes. They do not scatter a beam of light, the particles do not separate by filtration and the particles do not settle down.
Explanation:
Materials Required
Beakers (250 mL), an iron stand, a glass rod, bunsen burner, test tube stand, three funnels, three tripod stands, filter papers, a small torch and China dish.
Chemicals Required
Common salt, sugar crystals, alum powder, chalk powder, fine sand, raw egg, fine soil from garden and distilled water.
Procedure
True solution of common salt:
Take a clean and dry beaker, pour 100 mL of distilled water in it and add dry common salt in it. Stir the content with a glass rod. Common salt dissolves completely to form a true solution.
True solution of sugar:
Take a clean and dry beaker and add 100 mL of distilled water in it, pour few sugar crystals in it arid stir the content with a glass rod. The sugar dissolves in water to form true solution.
True solution of alum:
Take a clean and dry beaker, add 100 mL of distilled water in it and add a pinch of alum powder, stir with a glass rod. The alum dissolves in water to form a true solution.
