Question

Two equations to show amphoteric property of water

Answer 1

${\text{\underline{\underline{Amphoteric \ Property}}}}$

$\sf{It \ is \ that \ property \ in \ which \ the \ substance}$
$\sf{will \ show \ acidic \ and \ basic \ behaviour.}$

$\sf{Ex \ : \ Water, \ Aluminium, \ etc.}$

$\sf{\underline{Water \ -}}$

$\bold{1. \ As \ Base}$

$\sf{HCl \ + \ H_2O \rightarrow H_3O^+ \ + \ Cl^-}$

$\bold{2. \ As \ Acid}$

$\sf{NH_3 \ + \ H_2O \rightarrow {NH_4}^{+} \ + \ OH^-}$
