Question
Which product is formed when carbon dioxide and water react in the same ratio?
✓

Answer

CO2 dissolves in water, and some of it reacts with water molecules to produce a slightly acid solution called carbonic acid. The (aq) indicates water solution. The hydrogen carbonate compound cannot be isolated as a pure substance - it decomposes easily to produce water and CO2 gas. Carbon Dioxide when dissolved in water leads to the formation of a weak acid which is called carbonic acid.

$\text{CO}_2(\text{aq})+\text{H}_2\text{O}\rightarrow\text{H}_2\text{CO}_3(\text{aq})$
