WebIron rejection as hematite from hydrometallurgical process solutions appears to be advantageous for a number of reasons. These include its environmental stability, low … WebLead thiocyanate, Pb(SCN)2, has a Ksp value of 2.00×10^−5. 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.
