Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): Barium carbonate is insoluble in water and is highly stable.
Reason (R): The thermal stability of the carbonates increases with increasing cationic size.
Choose the most appropriate answer from the options given below:
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): Barium carbonate is insoluble in water and is highly stable.
Reason (R): The thermal stability of the carbonates increases with increasing cationic size.
Choose the most appropriate answer from the options given below:
Option 1 -
(A) is false but (R) is true.
Option 2 -
(A) is true but (R) is false
Option 3 -
Both (A) and (R) are true but (R) is not the true explanation of (A).
Option 4 -
Both (A) and (R) are true and (R) is the true explanation of (A).

Correct Option - 4
Detailed Solution:In alkaline earth metals cationic size increases down the groups, hence thermal stability of carbonates increases down the group. Therefore both assertion and reason are correct and reason is correct explanation of assertion.
