Question

Complete the following reaction:
$2\mathrm{NaOH}\left(\mathrm{aq}\right)+H_2{\mathrm{SO}}_4\left(\mathrm{aq}\right)\to$

• A. ${\mathrm{Na}}_2{\mathrm{SO}}_4\left(\mathrm{aq}\right)+2H_{2}O\left(l\right)$
• B. ${\mathrm{Na}}_{2}O\left(\mathrm{aq}\right)+2H_{2}O\left(l\right)$
• C. ${\mathrm{Na}}_{2}O\left(\mathrm{aq}\right)+2H_{2}O\left(l\right)+{\mathrm{SO}}_2\left(g\right)$
• D. ${\mathrm{Na}}_2{\mathrm{SO}}_4\left(\mathrm{aq}\right)+2H_{2}S\left(g\right)$

Answer 1

The correct option is A ${\mathrm{Na}}_2{\mathrm{SO}}_4\left(\mathrm{aq}\right)+2H_{2}O\left(l\right)$

$\text{NaOH}$ is a base and ${\text{H}}_2{\text{SO}}_4$ is an acid. An acid reacts with a base to give salt and water. This type of reaction is known as neutralisation reaction.

Therefore, $\text{NaOH}$ reacts with ${\text{H}}_2{\text{SO}}_4$ to produce ${\text{Na}}_2{\text{SO}}_4$ and ${\text{H}}_2\text{O}$.
The chemical reaction is given below:

$2\mathrm{NaOH}\left(\mathrm{aq}\right)+H_2{\mathrm{SO}}_4\left(\mathrm{aq}\right)\to {\mathrm{Na}}_2{\mathrm{SO}}_4\left(\mathrm{aq}\right)+2H_{2}O\left(l\right)$
