Question

Which of the following on thermal decomposition yields a basic as well as an acidic oxide?
A. `CaCO_(3)`
B. `NH_(4)NO_(3)`
C. `NaNO_(3)`
D. `KClO_(3)`

Answer 1

Correct Answer - A::B
`NaNO_(3) overset(Delta)(rarr) NaNO_(2)+1//2 O_(2)`
`2KClO_(3) overset(Delta)(rarr) 2KCl+3O_(2)`
Metal oxides are bases non metallic oxides are acidic except `CO, NO, H_(2)O, N_(2)O` are netural oxide.
