A chemist dissolved 65.353 grams of CuSO4 * 5H2O into enough water to make 150.0 mL of aqueous CuSO4 solution. (a) Calculate the concentration of this solution, in molarity. (b) What is the normality of the Cu2+ ions in the above solution? (c) He then reacted the above CuSO4 solution with some 0.225 M KI solution. The reaction occurs as follows: 2 CuSO4 (aq) + 4 KI (aq) à 2 CuI (s) + I2 (aq) + 2 K2SO4 (aq)...
