Short Note
The solubility of ammonium chloride in water at various temperatures is given below :
| Temperature | : | 10°C | 20°C | 40°C | 60°C | 80°C |
| Solubility | : | 24 g | 37 g | 41 g | 55 g | 66 g |
What mass of ammonium chloride would be needed to make a saturated solution of ammonium chloride in fifty grams of water at 40°C ?

Solution
Given that,
Solubility at 40°C = 41 gm
solubility = Solid dissolved in 100 grams of water in a solution
So, mass of ammonium chloride, required to make a saturated solution of ammonium chloride, in 50 gm of water at 40°C = `41/2g=20.5 gm`
