Question

Assertion: Metal oxides are basic in nature.

Reason: Metal oxides neutralise the effect of acids and release water, similar to the reaction of a base with an acid.

• A. Both assertion and reason are true and the reason is the correct explanation of assertion.
• B. Both assertion and reason are true but the reason is not the correct explanation of assertion.
• C. Only assertion is correct.
• D. Only reason is correct.

Answer 1

The correct option is A Both assertion and reason are true and the reason is the correct explanation of assertion.

Metal oxides react with acids to form salt and water, similar to the reaction of a base with an acid. Hence, metal oxides are basic in nature.
For example:
$MgO+2HCl\to MgC{l}_2+H_{2}O$
