Problem: Consider the following acid-neutralization reactions involving the strong base NaOH(aq):HNO3(aq) + NaOH(aq) → NaNO3(aq) + H2O(l)HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l)NH4+(aq) + NaOH(aq) → NH3(aq) + Na+(aq) + H2O(l)Write net ionic equations for the neutralization of the hydrochloric acid.

FREE Expert Solution

We are asked to write the net ionic equation for the neutralization of hydrochloric acid.


HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l)


Dissociate the aqueous species to ions: 

H+(aq) + Cl-(aq) + Na+(aq)  + OH-(aq) →Na+(aq)  + Cl-(aq)  + H2O(l)
