Question

2. Predict the products of the reaction and write its balanced molecular equation (6 pts), ionic equation (4 pts) and net ionic equation (3 pts). Pb(NO,): + KCl→

Answer 1

Pb(NO3)2(aq) + KCl(aq) ----------------

Aqueous solution of Lead(II)nitrate is on reacts with aqueous solution of Potassium chloride to give solid Lead(II)chloride and aqueous solution of Potassium nitrate.

Pb(NO3)2(aq) + 2 KCl(aq) --------------- PbCl2(s) + 2 KNO3(aq)

Pb+2(aq) + 2 NO3-(aq) + 2 K+(aq) + 2 Cl-(aq) ----------------- PbCl2(s) + 2 K+(aq) + 2 NO3-(aq)

spectator ions K+ and NO3- ions are cancelled on both sides

Pb+2(aq) + 2 Cl-(aq) -------------- PbCl2(s).
