Which of the following on thermal decomposition yields a basic as well as an acidic oxide?

A

`KClO_(3)`

B

`Na_(2)CO_(3)`

C

`NaNO_(3)`

D

`CaCO_(3)`

Text Solution

Verified by Experts

The correct Answer is:
D
Thermal decompostion of `CaCO_(3)` gives both basic oxide as well as acidic oxide.
`CaCO_(3) to underset("oxide")underset("Basic")(CaO)+underset("oxide")underset("acidic")(CO_(2))`
Metal oxides are basic in nature where as nonmetals oxides are acidic in nature.
