Question
An aqueous solution of lead (II) nitrate is mixed with anaqueous solution of potassium iodide. The products of the reactionare potassium nitrate (which remains in solution) and lead (II)iodide ( which precipitates). Write a molecular, full ionic and netionic equation for the reaction. (indicate phases --g,l,aq or s) An aqueous solution of lead (II) nitrate is mixed with anaqueous solution of potassium iodide.

(indicate phases --g,l,aq or s)Explanation / Answer
Molecular Equation---------------------- Pb(NO3)2 ( aq) + 2KI ( aq) ------> 2 KNO3 (aq) + PbI2(s) Ionic Equation ---------------- Pb 2+ (aq) + 2 NO3- (aq) + 2K + (aq) + 2 I- (aq) -------> 2K + (aq) +2NO3- (aq) + PbI2 ( s) Spectator ions : NO3- & K+ Net ionic Equation ---------------------- Pb 2+ (aq) + 2 I- (aq) -------> PbI2 (s) Net ionic Equation ---------------------- Pb 2+ (aq) + 2 I- (aq) -------> PbI2 (s) Pb 2+ (aq) + 2 I- (aq) -------> PbI2 (s)
