When an aqueous solution of sodium hydroxide (NaOH) reacts completely with a solution of hydrochloric acid (HCl), the reaction occurs according to the following equation:
\[ \text{NaOH (aq)} + \text{HCl (aq)} \rightarrow \text{NaCl (aq)} + \text{H}_2\text{O (l)} \]
In this reaction, sodium hydroxide and hydrochloric acid react to form sodium chloride (NaCl) and water (H₂O).
After all the water evaporates from the reaction mixture, what will remain is solid sodium chloride (NaCl), also known as table salt. Therefore, the final residue left after evaporation will be sodium chloride.
