Question

Assertion: Copper liberates hydrogen from a solution of dilute hydrochloric acid.
Reason: Hydrogen is above copper in the electro- chemical series.
A. If both assertion and reason are true and the reason is the correct explanation of the assertion.
B. If both assertion and reason are true but reason is not the correct explantion of the assertion.
C. If assertion is true but reason is false.
D. If assertion is false but reason is true.

Answer 1

Correct Answer - D
`Cu` cannot liberate `H_(2)` from a solution of dilute `HCl` as hydrogen is above copper in the electrochemical series.
`E_(H^(+//_(1//2)H_(2)))^(@)=+-0.00` , `E_(Cu^(2+//_(Cu))=+0.34`.
