Answer 1

Answer:

Question :-

if 'x' g of potassium nitrate is added to 100g of water at 60°c and the salt dissolves completely then-

(a) is X g. the solubility of potassium nitrate at 60°c. ?

Answer :-

Add X g of solute i.e. potassium nitrate to 100 g of water 60°C.

1. Stir the solute i.e. potassium nitrate in water thoroughly.

2. X g of the solute completely dissolves in water.

3. Add more solute and again stir thoroughly.

4. The solute continues to dissolves.

5. Water i.e. the solvent can dissolve more of the solute at the given temperature.

6. Therefore the solution is said to be unsaturated. Therefore, the solubility is more than X g and not X g.

Answer 2

Explanation:

Question :-

if 'x' g of potassium nitrate is added to 100g of water at 60°c and the salt dissolves completely then-

(a) is X g. the solubility of potassium nitrate at 60°c. ?

$\mathbb\red{ \tiny A \scriptsize \: N \small \:S \large \: W \Large \:E \huge \: R}$

Add X g of solute i.e. potassium nitrate to 100 g of water 60°C.

1. Stir the solute i.e. potassium nitrate in water thoroughly.

2. X g of the solute completely dissolves in water. 3. Add more solute and again stir thoroughly.

4. The solute continues to dissolves.

5. Water i.e. the solvent can dissolve more of the solute at the given temperature.

6. Therefore the solution is said to be unsaturated.

Therefore, the solubility is more than X g and not X g .
