Asked by J.M.
a) How many grams of KNO_3 should be added to 100 mL of water at 25°C to make a saturated solution?
b) The solubility of KNO_3 increases as temperature increases. When KNO_3 dissolves, is the process endothermic or exothermic?
c) When CaCl_2 dissolves, the process if exothermic. Is CaCl_2 more soluble at high temperature or low temperatures?
