Question

Use the given K. values to predict which of the following salts is the most soluble, in terms of moles per liter, in pure water. (Hint: The size of Ksp tells us about solubility in general. The tutorial will explain the math but comparing the values for the general solubility is sufficient for these since they are all 1:2 ratios of ions.) Special note: mercury(I) ions forms a dimer and behaves like a polyatomic ion. So, Hg,X, breaks into Hg2+ + 2x There is only ONE submission for this question. Ag, Croc, Ksp= 1.1e-12 PbCI,, Ksp= 1.7e-05 Pb(OH), Ksp= 1.4e-20 Hg,F, Ksp= 3.1e-06 Ag, cro PbCl2 Pb(OH)2 o Hg,F,
