The chemical formula for sodium hydrogen tetraoxosulphate(VI) is \( \text{NaHSO}_4 \), and the chemical formula for sodium hydroxide is \( \text{NaOH} \).
When sodium hydrogen tetraoxosulphate(VI) reacts with sodium hydroxide, it can undergo a neutralization reaction. The balanced chemical equation for this reaction is:
\[ \text{NaHSO}_4 + \text{NaOH} \rightarrow \text{Na}_2\text{SO}_4 + \text{H}_2\text{O} \]
In this reaction, sodium hydrogen tetraoxosulphate(VI) reacts with sodium hydroxide to form sodium sulfate and water.
