Question

. Solubility of potassium nitrate at 313 K is 62 g. What mass of potassium nitrate would be needed to produce a saturated solution of KNO3 in 52 g of water at 313 K? What is the effect of change of temperature on the solubility of a salt?

Answer 1

Answer:

The solubility of KNO3 is 62g KNO3 in 100g H2O at 313K

That is how I interpret your statement.

This is the maximum amount of solute that can be dissolved in water at 313K. The solution is saturated at that temperature.

If you have only 50g H2OP you will dissolve only half the mass of KNO3

Mass KNO3 = 62/2 = 31g . KNO3 soluble in 50g H2O at 313K.

Answer 2

Answer:

This is the maximum amount of solute that can be dissolved in water at 313K. The solution is saturated at that temperature. Mass KNO3 = 62/2 = 31g . KNO3 soluble in 50g H2O at 313K.
