Question

A saturated solution of silver nitrate is prepared in 100g of water at 20c. The solution is then heated to 50c. How much more silver nitrate must now be added to obtain a saturated solution?

Answer 1

233 g.

Step-by-step explanation:

• It is known that:

The solubility of silver nitrate at 20.0°C is 222 g per 100 g of water.

The solubility of silver nitrate at 50.0°C is 455 g per 100 g of water.

∴ We need to add (455 g - 222 g = 233 g) of AgNO₃ to obtain a saturated solution at 50.0°C.
