In carbonated soft drinks, dissolved carbon dioxide reacts with water to form carbonic acid:
carbon dioxide+water⇌carbonic acid \text{carbon dioxide} + \text{water} \rightleftharpoons \text{carbonic acid} carbon dioxide+water⇌carbonic acidThe symbol ⇌ \rightleftharpoons\,⇌ indicates that carbonic acid can decompose back into carbon dioxide and water at the same time as the forward reaction occurs.
State the term used to describe this type of chemical reaction.
