Question

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

Answer 1

You need the solubility cure for AgNO3 to answer this. Then simply look up the saturation level of the salt at 50 oC and subtract the amount at 25 oC
