What is the solubility of PbSO4 in a solution which originally was 0.050 M in Pb(NO3)2?
#5 Write the solubility product expression for PbCl2. Using the concentration for the Pb+2 and Cl- ions, solve for your experimental Ksp. #6 Using your book, find the theoretical Ksp for PbCl2 to determine your percent error A Solubility Product Constant Introduction: Many substances are very soluble in water. However, in this experiment you will be concerned with substances that are insoluble or only slightly soluble. Dynamic equilibrium is established when an excess of a slightly soluble substance is placed...
