प्रश्न
Assertion: \[\ce{Cu}\] cannot liberate hydrogen from acids.
Reason: Because it has positive electrode potential.
विकल्प
Both assertion and reason are true, and reason is the correct explanation of the assertion.
Both assertion and reason are true but reason is not the correct explanation of assertion.
Assertion is not true but reason is true.
Both assertion and reason are false.
उत्तर
Both assertion and reason are true, and reason is the correct explanation of the assertion.
Explanation:
\[\ce{Cu}\] lies below hydrogen in electrochemical series and has positive electrode potential. hence cannot liberate hydrogen from acids.
Both the statements assertion and reason are correct and reason is the correct explanation of assertion.
