Equilibrium Question 267
Question: Which equilibrium can be described as an acid-base reaction using the Lewis acid-base definition but not using the Bronsted-Lowry definition [AIIMS 1980]
Options:
A) $ 2NH_3+H_2SO_4 $ ⇄ $ 2NH_4^{+}+SO_4^{2-} $
B) $ NH_3+CH_3COOH $ ⇄ $ NH_4^{+}+CH_3CO{O^{-}} $
C) $ H_2O+CH_3COOH $ ⇄ $ H_3{O^{+}}+CH_3CO{O^{-}} $
D) $ {{[Cu{{(H_2O)}_4}]}^{2+}}+4NH_3 $ ⇄ $ {{[Cu{{(NH_3)}_4}]}^{2+}}+4H_2O $
