Answer: Option (a) is the correct answer.
Explanation:
A dissociation reaction is defined as the reaction in which a compound beaks down into two or more different parts.
For example, molecular formula of water is [tex]H_{2}O[/tex] and when it dissociates then it given hydrogen ion and hydroxide ion.
Therefore, dissociation reaction for water is as follows.
[tex]H_{2}O \rightleftharpoons H^{+} + OH^{-}[/tex]
Thus, we can conclude that out of the given options [tex]H_{2}O \rightleftharpoons H^{+} + OH^{-}[/tex] is the correct equation for the dissociation of water.
