For any problems in which you utilize a spreadsheet program, please print at least the first page of the spreadsheet and show all formulas as you enter them into the program. 1. The K sp of Hg 2 Cl 2 is 1.43 x 10 -18 at 25 ° C. a. Calculate the molar solubility (S) of Hg 2 Cl 2 in water with and without activity corrections at pH = 7.000. You may neglect hydrolysis of the metal. b. Calculate the molar solubility (S) of Hg 2 Cl 2 in 0.0100 M NaCl with and without activity corrections at pH = 7.000. You may neglect hydrolysis of the metal. 2. The K sp of Cu 3 (PO 4 ) 2 is 1.40 x 10 -37 at 25 ° C. a. Calculate the molar solubility (S) of Cu 3 (PO 4 ) 2 in pure water at pH = 7.000. Neglect activity corrections, hydrolysis of the metal, and formation of H x PO 4 species. b.
