Problem: Complete and balance the following chemical reactionsPb(NO3)2 (aq) + 2 KCl (aq) →

FREE Expert Solution

The given reaction is: 

Pb(NO3)2 (aq) + 2 KCl (aq) →

Split the reactants into ions and swap them to form the products. 

KCl (aq) → K+(aq) + Cl-(aq)

Pb(NO3)2 (aq)  → Pb2+(aq) + NO3-(aq)


  • K+(aq) + NO3-(aq) → KNO3(aq)
  • Pb2+(aq) + Cl-(aq) → PbCl2(s)

Recall that when balancing chemical equations, we have to make sure that the number of elements on both sides is equal with the lowest whole number coefficients.

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