Question

what weight of sodium nitrate will separate when decorated solution containing 50 gram of water is cooled from 50 degree Celsius to 30 degree Celsius the solubility of Sodium Nitrate 50 and 30 degree celsius is 114 gram and 86 gram respectively​

Answer 1

Answer:

100g of water will dissolve 114g of sodium nitrate at 50 degree celsius and 86 g at 30 degree celsius.

1 g of water will dissolve 1.14 g of sodium nitrate at 50 degree celsius and 0.86 g at 30 degree celsius.50 g of water will dissolve 1.14×50=57 g of sodium nitrate at 50 degree celsius and 0.86×50=43 g at 30 degree celsius.

Separation of sodium nitrate out of saturated solution is due to decrease in solubility of sodium nitrate in water with decrease in temperature.

Weight that will separate out from 50 g of water =57−43g=14 g.
