Question

Complete the following reaction:

${\text{H}}_2{\text{SO}}_4+2\text{NaOH}\to$

• A. $2{\text{Na}}_2{\text{SO}}_4+4{\text{H}}_2\text{O}$
• B. $2{\text{Na}}_2{\text{SO}}_4+{\text{H}}_2\text{O}$
• C. ${\text{Na}}_2{\text{SO}}_4+2{\text{H}}_2\text{O}$
• D. $2{\text{Na}}_2{\text{SO}}_4+{\text{H}}_2\text{O}$

Answer 1

The correct option is C

${\text{Na}}_2{\text{SO}}_4+2{\text{H}}_2\text{O}$

Acids on reaction with a base give salt and water. This reaction between an acid and a base is called a neutralisation reaction. The given reaction is a neutralisation reaction. Here the acid is sulphuric acid ${\text{H}}_2{\text{SO}}_4$ and the base is $\text{NaOH}$. This reaction will give salt ${\text{Na}}_2{\text{SO}}_4$ and water ${\text{H}}_2\text{O}$. The reaction will occur as follows:

${\text{H}}_2{\text{SO}}_4\text{(aq)}+2\text{NaOH (aq)}\to {\text{Na}}_2{\text{SO}}_4\text{(s)}+2{\text{H}}_2\text{O (l)}$
