${\text{Na}}_2{\text{CO}}_3\text{(aq)}+{\text{H}}_2{\text{SO}}_4\text{(aq)}\to ?$

• A. ${\mathrm{Na}}_2{\mathrm{SO}}_4\left(\mathrm{aq}\right)+{\mathrm{SO}}_2\left(g\right)+H_{2}O\left(l\right)$
• B. ${\mathrm{Na}}_2{\mathrm{SO}}_4\left(\mathrm{aq}\right)+{\mathrm{CO}}_2\left(g\right)+H_{2}O\left(l\right)$
• C. ${\mathrm{Na}}_2{\mathrm{SO}}_4\left(\mathrm{aq}\right)+{\mathrm{CO}}_2\left(g\right)+H_2\left(g\right)$
• D. ${\mathrm{NaHSO}}_4\left(\mathrm{aq}\right)+{\mathrm{CO}}_2\left(g\right)+H_{2}O\left(l\right)$

Answer 1

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

The given chemical equation depicts the reaction between sodium carbonate (${\text{Na}}_2{\text{CO}}_3$) and sulphuric acid (${\text{H}}_2{\text{SO}}_4$). They react with each other to form sodium sulphate (${\text{Na}}_2{\text{SO}}_4$) , carbon dioxide (${\text{CO}}_2$) and water (${\text{H}}_2\text{O}$). The reaction involved is given below:

${\text{Na}}_2{\text{CO}}_3\text{(aq)}+{\text{H}}_2{\text{SO}}_4\text{(aq)}\to {\text{Na}}_2{\text{SO}}_4\text{(aq)}+{\text{CO}}_2\text{(g)}+{\text{H}}_2\text{O}\text{(l)}$
