Question

Assertion: zinc oxide is amphoteric in nature Reason: zinc oxide reacts with both acids and bases *
a. if both assertion and reason are true, and reason is the correct explanation of assertion.
b. if both assertion and reason are true, and reason is not the correct explanation of assertion
c. If assertion is true but reason is false
d. if assertion is false and reason is true​

Answer 1

Answer:

answer is a both assertion and reason are correct

Answer 2

Both assertion and reason are correct statements and reason is the correct explanation of assertion. Thus, the correct option is (a).

Explanation:

• A compound is considered to have an amphoteric nature if it reacts with both an acid and a base.
• Zinc oxide can react with an acid such as hydrochloric acid to form zinc chloride and water.
• The reaction is given as: $\[ZnO + 2HCl \to ZnC{l_2} + {H_2}O\]$

• It also reacts with a base such as sodium hydroxide to form sodium zincate and water.
• The reaction is given as: $\[ZnO + 2NaOH \to N{a_2}Zn{O_2} + {H_2}O\]$
• Thus, zinc oxide is amphoteric in nature because it reacts with both an acid and a base.
• Hence, both assertion and reason are correct statements and reason is the correct explanation of assertion.
