Question

Describe how water reacts with Carbon dioxide state experimental conditions and write the balanced chemical equation.

Answer 1

• When carbon dioxide reacts with water Carbonic acid is formed. from which hydrogen ion dissociates increasing the acidity of the system.
• Hence in addition to any greenhouse effect, carbon dioxide emission to the atmosphere can increase the acidity of the atmosphere and precipitation.
• When carbon dioxide reacts with water a weak acid is formed.
• As carbon dioxide is present in the air is blown into the flask containing an indicator sensitive to small changes in the PH.
• There are consequent colour changes observed.
• The chemical reaction between water and carbon dioxide is :
• $\underset{\mathrm{carbon}\mathrm{dioxide}}{\underset{}{{\mathrm{CO}}_2\left(\mathrm{g}\right)}}+\underset{\mathrm{water}}{\underset{}{{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}}\iff \underset{\mathrm{carbonic}\mathrm{acid}}{\underset{}{{\mathrm{H}}_2{\mathrm{CO}}_3\left(\mathrm{aq}\right)}}$
