S. No. | Substance dissolved (in gram) | |||
1. | Ammonium chloride | 37 g | 41 g | 55 g |
2. | Potassium chloride | 35 g | 40 g | 46 g |
3. | Sodium chloride | 36 g | 36 g | 37 g |
4. | Potassium nitrate | 32 g | 62 g |
Answer:
(i)
Potassium nitrate (1)
(ii) Potassium nitrate (1)
(iii) At 333K, ammonium chloride dissolved per 100g =55g
At 293K, ammonium chloride dissolved perl00g=37g
When solution is cooled from 333K to 293K, amount of
ammonium chloride that will separate out =55g-37g=18g. (1)
(iv) Solubility of a salt (soild) increases with rise in
temperature and vice-versa. (1)
(v) At 293K, amount of NaCI dissloved in 100g water = 36 g
At 293K amount of NaCI
dissolved
in 10g water (1)
