Vedclass · Answer

(C) In the auto-ionization reaction of water,$2H_2O \rightleftharpoons H_3O^{+} + OH^{-}$,one water molecule acts as a Bronsted-Lowry acid by donating a proton $(H^{+})$ to form $OH^{-}$.Another water molecule acts as a Bronsted-Lowry base by accepting a proton $(H^{+})$ to form $H_3O^{+}$.Since water performs both functions,it is amphoteric and acts as both a weak acid and a weak base.

In the reaction $2H_2O \rightleftharpoons H_3O^{+} + OH^{-}$,water is
