1. Why does adding sodium chloride to a saturated solution of lead chloride reduce the solubility of PbCl2?
Equilibrium is pushed toward the left in the equation
Naci(s)=Na+ (aq) + Cr (aq).
O Equilibrium is pushed toward the left in the equation
PbCl2 (s)=Pb2+ (aq) + 2Cr (aq).
O Equilibrium is pushed toward the right in the equation
Pbci, (s)= Pb2+ (aq) + 2Cr (aq).
O Equilibrium is pushed toward the right in the equation
Naci(s)=Na+ (aq) + Cr(aq).
