Equilibrium Question 268
Question: The hydride ion $ {H^{-}} $ is stronger base than its hydroxide ion $ O{H^{-}}. $ Which of the following reaction will occur if sodium hydride $ (NaH) $ is dissolved in water [CBSE PMT 1997]
Options:
A) $ {H^{-}}(aq)+H_2O,\to ,H_2O $
B) $ {H^{-}},(aq)+H_2O,(l),\to ,O{H^{-}}+H_2 $
C) $ {H^{-}},+H_2O,\to $ No reaction
D) None of these
Show Answer
Answer:
Correct Answer: B
Solution:
$ {H^{-}} _{\text{(aq}\text{.)}}+H_2{O _{(l)}}\to O{H^{-}}+H_2 $ .
