Question

50 gram of water saturated with silver nitrate at 60°c is cooled to 25°c . calculated the mass of silver nitrated deposited . the solubiliTy of silver nitrate at 60°c and 25°C are 420 and 180 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.
