Question

Assertion: The more negative the standard reduction potential, the more is its ability to displace hydrogen from acids.

Reason: Ability to displace hydrogen from acids translates to the strength of the reductant.

• A. Both Assertion and Reason are true and Reason is the correct explanation of Assertion
  
• B. Both Assertion and Reason are true but Reason is not the correct explanation of Assertion
• C. Assertion is true but Reason is false
• D. Assertion is false but Reason is true
• E. Both Assertion and Reason are false

Answer 1

The correct option is A Both Assertion and Reason are true and Reason is the correct explanation of Assertion

The standard cell potential is the potential difference between the cathode and anode. The standard reduction potential is the likelihood that a species will be reduced. Universally, hydrogen has been recognized as having reduction and oxidation potentials of zero. Therefore, when the standard reduction and oxidation potential of chemical species are measured, it is actually the difference in the potential from hydrogen.The more negative the standard reduction potential, the more is its ability to displace hydrogen from acids.
