Predict the solubility change (increase, decrease, or no change) of the following compounds. Explain your choice in details.   (a) Cu(OH)2 when adding HCl solution   (b) AgI when adding HCl solution   (c) PbCl2 when adding KCl solution

A solution contains CO32– at a concentration of 0.0023 M and Cl– at a concentration of 0.00076 M. If AgNO3(aq) is added drop by drop to the solution, which ion, CO32– or Cl–, will precipitate first? Give the minimum concentration of Ag+ needed to precipitate each of the
