There is a solution of a mixture of the following: AgNO_3 Hg_2^2+ ions, and Pb/NO_3)_2. The Ksp values: for PbCl_2 is 2.4 times 10^-4: for AgCl is 1.6 times 10^-10: for Hg_2Cl_2 is 1.0 times 10^-18. If the concentration each of the metal ions in solution is 0.050 M and a volume of 0.250 L, give the order in which the metal ions will precipitate out by adding 1.00 M HCl. What volume HCl is needed to precipitate the first ion?
