Question

Selenous acid is diprotic it can react with sodium hydroxide in steps write equations (in molecular form) for the two steps of the reaction

Answer 1

The chemical formula for the selenous acid is H2SeO3. Its reaction with sodium hydroxide, which has a chemical formula of NaOH, will be a neutralization reaction forming a salt and water. This is depicted below.

H2SeO3 + NaOH à Na2SeO3 + H2O

If we are to balance the chemical reaction then, we will have a final answer of,

H2SeO3 + 2NaOH à Na2SeO3 + 2H2O
