Question

$\mathrm{NaOH}+{\mathrm{H}}_2{\mathrm{SO}}_4\to {\mathrm{Na}}_2{\mathrm{SO}}_4+{\mathrm{H}}_2\mathrm{O}$, Balance it.

Answer 1

Balanced chemical reaction:-

1. A chemical reaction is said to be balanced when the total number of the atoms present in the reactant as well as product side are equal.
2. Chemical reaction is basically written in the symbolic representation form which is known as chemical equation.
3. Therefore, the balanced chemical equation for the above is:

$\underset{\mathrm{Sodium}\mathrm{hydroxide}}{2{\mathrm{NaOH}}_{\left(\mathrm{aq}\right)}}+\underset{\mathrm{Sulphuric}\mathrm{acid}}{{\mathrm{H}}_2{\mathrm{SO}}_{4\left(\mathrm{aq}\right)}}\to \underset{\mathrm{Sodium}\mathrm{sulphate}}{{\mathrm{Na}}_2{\mathrm{SO}}_{4\left(\mathrm{aq}\right)}}+\underset{\mathrm{Water}}{2{\mathrm{H}}_2{\mathrm{O}}_{\left(\mathrm{l}\right)}}$
