Chemistry - Ionic Equilibrium Question with Solution | TestHub

$\mathrm{N}{\mathrm{a}}_2\mathrm{C}{\mathrm{O}}_3$is the salt of strong base and weak acid.
$\begin{array}{ccccccc}{\text{Na}}_2{\text{CO}}_3& +& 2{\text{H}}_2\text{O}& \to & 2\text{NaOH}& +& {\text{H}}_2{\text{CO}}_3\\ & & & & \text{Strong base}& & \text{Weak acid}\end{array}$
Hence, the solution of$\mathrm{N}{\mathrm{a}}_2\mathrm{C}{\mathrm{O}}_3$has pH greater than 7.
