as defined by Arrhenius acid base reactions r characterised by acids which dissociated in aqueous solution.to form hydrogen ions and bases which form hydroxide ions.acids r defined as a compound or element that releases h+ions into the solution mainly water.

Answer 2

$\textbf{\large{Answer -}}$

Those substances which gives ${H}^{+}$ ion in aqueous solution are known as acid.

Example :

$HCl (aq) ==> {H}^{+} (aq) + {Cl}^{-}$

$CH_{3}COOH (aq) ==> CH_{3}{COO}^{-} (aq) + {H}^{+} (aq)$

Those substances which gives ${OH}^{-}$ ion in aqueous solution are known as bases.

Example :

$NaOH (aq) ==> {Na}^{+} (aq) + {OH}^{-} (aq)$

$KOH (aq) ==> {K}^{+} (aq) + {OH}^{-} (aq)$
