Solution
Verified by Toppr
(A) H2O+NH3⇌NH4+OH−
Here NH3 is Lewis base and H2O
acid as acid to it represents
acidic nature of H2O
(b)FeCl3+H2O→Fe(OH)3+3HCl
it is are example of hydrolysis
reaction which produces acid and base
(C) H2O+H2o→H3O+OH−
self ionisation of water
(D) 2H2O→2H2+O2
Decomposition of water in their
corresponding molecule
(A)-(iii), (B)-(iv), (C)-(i), (D)-(ii)
