JEE · NEET Previous Year Question
The metal that cannot be obtained by electrolysis of an aqueous solution of its salts is :
Topic: JEE PYQ
Answer: B. Full step-by-step solution below.
- AAg
- BCa
- CCu
- DCr
Correct answer: B
Solution
(b) Reason : Higher the position of element in the electrochemical series, more difficult is the reduction of its cations. If (aq) is electrolysed, water is reduced in preference to it. Hence it cannot be reduced electrolytically from an aqueous solutions.More Electrochemistry PYQs
