Question

Statement: The oxides of copper can be reduced into copper by heating alone.
Reason: Low active metals can be reduced easily by heating.

Which of the following holds true?

• A. Only Statement is true but the Reason is false.
• B. Only Reason is true but the Statement is false.
• C. Both Statement and Reason are true and Reason is the correct explanation for Statement.
• D. Both Statement and Reason are true but Reason is not the correct explanation for Statement.

Answer 1

The correct option is C Both Statement and Reason are true and Reason is the correct explanation for Statement.

Metals can be put under the categories of highly active, moderately active and low active metals. Oxides of highly active metals can be reduced by electrolytic reduction while that of moderately active metals can be reduced by using reducing agents such as carbon. Oxides of low active metals can be reduced by heating alone.
Copper is a low active metal whose oxide can be reduced by heating alone to obtain copper metal.
