The solubility of KNO 3 at 75 degrees celsius is 155g per 100 g of water, and at 25 degrees celsius it is 38.0g per 100 g of water. What mass in grams will crystallize out of the solution if exactly 100.0 g of the saturated solution at 75 degrees celsius is cooled down to 25 degrees celsius? Anion is a conjugate base of a weak acid. Then the solubility will always increase with decreasing pH. In other words, if you added and acid. So anytime to wanted to increase the solubility of a salt if you look at the anion and it is the conjugate base of a weak acid then you would be able to increase the solubility by adding acid.
