$\text{H}\text{C}{\text{O}}_3^{-}$and$\text{C}{\text{O}}_3^{2-}$will produce odourless gas i.e. carbon dioxide with$\mathrm{\text{d}}\mathrm{\text{i}}\mathrm{\text{l}}.{\text{H}}_2\text{S}{\text{O}}_4.$

$\underset{\mathrm{\text{Baking soda}}}{\text{NaHC}{\text{O}}_3}\left(\text{a}\text{q}\right)+{\text{H}}_2\text{S}{\text{O}}_4\left(\text{a}\text{q}\right)\to \text{N}{\text{a}}_2\text{S}{\text{O}}_4\left(\text{a}\text{q}\right)+2\text{C}{\text{O}}_2\left(\text{g}\right)+2{\text{H}}_2\text{O}\left(\text{l}\right)$

$\underset{\mathrm{\text{Washing soda}}}{\text{N}{\text{a}}_2\mathit{\text{CO}}}+{\text{H}}_2\text{S}{\text{O}}_4\left(\text{a}\text{q}\right)\to \text{N}{\text{a}}_2\text{S}{\text{O}}_4\left(\text{a}\text{q}\right)+{\text{H}}_2\text{O}\left(\text{l}\right)+\text{C}{\text{O}}_2\left(\text{g}\right)$
