Question
Which of the following gives sodium hydroxide along with hydrogen gas on reaction with water ?
Options
A.Sodium ferrite
B.Sodium amalgam
C.Sodium peroxide
D.Sodium carbonate.
Solution
(A) 2NaFeO2 + H2O (hot) → 2 NaOH + Fe2O3 ;
(B) 2Na/Hg + 2H2O (Castner-Kellner cell) → 2NaOH + 2 Hg + H2.
(C) Na2O2 + 2H2O → 2NaOH + H2O2
(D) Na2CO3 + 2H2O → 2NaOH + H2CO3
(B) 2Na/Hg + 2H2O (Castner-Kellner cell) → 2NaOH + 2 Hg + H2.
(C) Na2O2 + 2H2O → 2NaOH + H2O2
(D) Na2CO3 + 2H2O → 2NaOH + H2CO3
