Question

what do you understand by the statement, '' The solubility of potassium nitrate in water at room temperature is 32 gram'' ? How will you prepare a saturated solution of potassium nitrate in water at 50 degree Celsius and what change will it show when it is cool down to the room temperature?​

Answer 1

Answer:

(a) Solubility of potassium nitrate at 100 g of water contains potassium nitrate = 62 g 50 g of water contains potassium nitrate Thus, 31 g potassium nitrate would be needed to produce a saturated solution of potassium nitrate in 50 g of water at 313 K
