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.
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.
Both (A) and (R) are true and (R) is the true explanation of (A)
(A) is true but (R) is false
Both (A) and (R) are true but (R) is not the true explanation of (A)
(A) is false but (R) is true.
Explanation
In IIA group on moving down the group size of cation increases and show thermal stability of carbonate increases.
