5. In our experiment, we took 5.00 ml of unknown solution consisting of Ca2+, Mg2+ to a 250 ml flask, add 30 mL of water , buffer ph 10, a few drops of indicator, and titrated using 20.00 mL of 0.04 M standard EDTA. What is molarity of unknown, M (Ca2+, Mg2+)? What effect did adding KCl to the solutions have on the solubility of KHT? and on the solubility product constant of KHT? Select one. The solubilty of KHT is? increased / decreased / no change and on the solubility product constant of KHT? increased / decreased / no change.
