Problem: What is the net ionic equation for the reaction that occurs when aqueous solutions of KOH and HNO3 are mixed?

FREE Expert Solution

We will have a double displacement reaction (i.e. cations and anions exchange):

KOH(aq) + HNO3(aq) → KNO3(aq) + H2O(l)


Before writing the net ionic equation we need to write the total ionic equation first:

• For the total ionic equation → soluble ionic compounds (in aqueous form) separate or breaks up and become ions

• Solids will not break up since they are insoluble compounds

KOH(aq) → K+(aq) + OH-(aq)

HNO3(aq) ) → H+(aq) + NO3-(aq)

KNO3(aq) → K+(aq) + NO3-(aq)

Total ionic equation:     K+(aq) + OH-(aq) + H+(aq) + NO3-(aq → H2O(l)+ K+(aq) + NO3-(aq)
