The common ion effect can be applied to a solution of lead thiocyanate when potassium thiocyanate is added. Since there is a common ion, the cyanate ion, the molar solubility of lead thiocyanate goes down in the presence of potassium thiocyanate Calculate the molar solubility of lead thiocyanate in 0.500 M KSCN Express your answer with the appropriate units. Lead thiocyanate, Pb(SCN)2, has a Ksp value of 2.00 x 10 5
