Ag_2SO_4 is a sparingly soluble salt with K_sp = 1.6 times 10. In which of the following solutions would the molar solubility of Ag_2SO_4 be the lowest? A. 0.10 M AgNO_3 B. 0.20 M AgNO_3 C. 0.20 M Na_2SO_4 D. 0.10 M Na_2SO_4 What will be the result if 100 mL of 0.06 M Mg(NO_3)_2 is added to 50 mL of 0.06 M Na_2C_2O_4? Assume the reaction is taking place at 25 degree C. No precipitate will form. A precipitate will form and an excess of Mg^2+ ions will remain in solution. A precipitate will form and an excess of C_2O_4^2- ions will remain in solution. A precipitate will form but neither ion is present in excess. product K_sp for Pb(IO_3)_2 is equal to 2.6 times 10^-13 at 25 degree C. What is of Pb(IO_3)_2 in pure water at 25 degree C? C. 6.0 times 10 mol/L D. 6.5 times 10^-14 mol/L
