Question

Write balanced equation for the following reactions:

Potassium hydrogen carbonate and dilute sulfuric acid.

Sodium nitrate and concentrated sulfuric acid.

Answer 1

The balanced chemical equation can be written as:

1. $$\begin{gathered} 2{\mathrm{KHCO}}_3\left(\mathrm{s}\right)+{\mathrm{H}}_2{\mathrm{SO}}_4\left(\mathrm{l}\right)\to {\mathrm{K}}_2{\mathrm{SO}}_4\left(\mathrm{s}\right)+2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)+2{\mathrm{CO}}_2\left(\mathrm{g}\right)\uparrow \\ (\mathrm{Potassium}(\mathrm{Dil}.\mathrm{Sulfuric}(\mathrm{Potassium}(\mathrm{water})(\mathrm{carbon} \\ \mathrm{hydrogen}\mathrm{acid})\mathrm{sulphate})\mathrm{dioxide}\left) \\ \mathrm{carbonate}\right) \end{gathered}$$
2. $$\begin{gathered} {\mathrm{NaNO}}_3\left(\mathrm{s}\right)+{\mathrm{H}}_2{\mathrm{SO}}_4\left(\mathrm{l}\right)\to {\mathrm{NaHSO}}_4\left(\mathrm{s}\right)+{\mathrm{HNO}}_3\left(\mathrm{l}\right) \\ (\mathrm{Sodium}(\mathrm{Conc}.\mathrm{sulfuric}(\mathrm{Sodium}(\mathrm{nitric} \\ \mathrm{nitrate})\mathrm{acid})\mathrm{sulphate})\mathrm{acid}) \end{gathered}$$
