Question

Assertion(A):Carbonates are polyatomic ions.

Reason (R):The carbonate ion consists of one carbon atom and three oxygen atoms and carries an overall charge of 2_

​

Answer 1

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

What is a carbonate?

• In the field of chemistry, a carbonate can be described as a polyatomic ion which is made up of a carbon atom and three atoms of oxygen.
• Carbonates are known to be the salts of carbonic acid.
• The formula for a carbonate ion is CO3 (2-).
• Hence, we know that both the assertion and the reason are correct. Also, the reason is proper explanation of the assertion as carbonate is a polyatomic molecule due to the carbon and oxygen ions.

Answer 2

Explanation:

Both A and R are correct and R is the correct explanation of A.
