On passing electric current over molten ionic hydrides of -block elements,
- A is liberated at the anode
- B is liberated at the cathode
- C No reaction takes place
- D Metal oxidises at the cathode
Answer & Solution
Correct Answer
(A) is liberated at the anode
Step-by-step Solution
Detailed explanation
When electric current is passed through an ionic hydride in the molten state, hydrogen gas is liberated at the anode. In hydrides of s-block hydrogen exist in -1 oxidation state. And it is oxidised into hydrogen gas. And oxidation always take place at anode. At anode:…
