Question

Write the balanced chemical equation for the following reaction:

Sodium sulphate using dilute Sulphuric acid.

Answer 1

Formation of Sodium sulphate:

• Dilute Sulphuric acid$\left(H_2{\mathrm{SO}}_4\right)$ and Sodium hydroxide $\left(\mathrm{NaOH}\right)$ reacts with each other to give Sodium sulphate $\left({\mathrm{Na}}_2{\mathrm{SO}}_4\right)$ and water$\mathbf{\left(}{\mathbf{H}}_{\mathbf{2}}\mathbf{O}\mathbf{\right)}$ as a product.
• This is an example of a neutralization reaction because acid is neutralized by a base leading to the formation of salt and water.

Balanced chemical equation:

$\underset{\mathrm{Sulphuric}\mathrm{acid}}{\underbrace{{\mathrm{H}}_2{\mathrm{SO}}_4\left(\mathrm{aq}\right)}}+\underset{\mathrm{Sodium}\mathrm{hydroxide}}{\underbrace{2\mathrm{NaOH}\left(\mathrm{aq}\right)}}\to \underset{\mathrm{Sodium}\mathrm{sulphate}}{\underbrace{{\mathrm{Na}}_2{\mathrm{SO}}_4\left(\mathrm{aq}\right)}}+\underset{\mathrm{water}}{\underbrace{2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}}$
