Plz solve no 4(a) and (b) as soon as possible.Useless answers will be reported ✌✌​

Answer 1

$\huge\underline\mathfrak\pink{ANSWER}$

(a). Take 100g of distilled water in a beaker. To this add one gram of copper sulphate crystals. Stir this mixture with the help of a glass rod and dissolve copper sulphate crystals. Similarly, go on dissolving more of copper sulphate solution, (1 gram) at a temperature time with constant and vigour stirring. A stage is reached when no more copper sulphate dissolves. It is called saturated solution at this temperature.

(b).Take this saturated solution of copper sulphate in a test tube and some more copper sulphate crystals. The crystals do not dissolve but settle down, which indicates that the solution is saturated.

Hope this answer will help you!!❤✌
