Question

Lead (II) chloride is formed by mixing solutions of Lead (II) nitrate and HCl. Upon mixing these solutions, the salt precipitates and establishes this equilibrium PbCl 2 (s) <---------> Pb 2+ (aq) + 2Cl - (aq) What would happen if a few crystals of solid KCl were added to this system? Answer a. More PbCl2 would precipitate because of LeChatlier's Principle b. The PbCl2 would dissolve because of LeChatlier's Principle c. The vessel holding the solution will feel colder because the reaction is endothermic. d. KCl would precipitate, because it is very insoluble

Explanation / Answer

a. More PbCl2 would precipitate because of LeChatlier's Principle
