Question

Write the chemical equation for the following activity.

Carbon dioxide gas was passed through the KOH solution.

Answer 1

When carbon dioxide gas is passed through the KOH solution, it forms potassium carbonate and water.

$$\mathrm{CO}{\phantom{A}}_2{\phantom{A}}_{(\mathrm{g})}+2\mathrm{KOH}{\phantom{A}}_{(\mathrm{aq})}⟶\mathrm{K}{\phantom{A}}_2\mathrm{CO}{\phantom{A}}_3{\phantom{A}}_{(\mathrm{aq})}+\mathrm{H}{\phantom{A}}_2\mathrm{O}$$
