Question
State the ions responsible for acidic and basic behaviour. Explain the acidic and basic behaviour by reaction with water.

Answer
$H ^{+}$or $H _3 O ^{+}$ions in aqueous solution are responsible for acidic character and $OH ^{-}$ions in an aqueous solution are responsible for basic character. $HCl \xrightarrow{H_2 O} Cl^{-}(aq)+H^{+}(aq)$ $H ^{+}$(aq) ions are formed in an aqueous solution of HCl . So, it can be said that HCl is an acid. $NaOH(s) \xrightarrow{H_2 O} Na^{+}(aq)+OH^{-}(aq)$ $OH ^{-}$ions are formed in an aqueous solution of $NaOH$ . So, it is a base.
