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

  • A
    $\mathrm{NaNO}_3$
  • B
    $\mathrm{KClO}_3$
  • Correct answer
    C
    $\mathrm{CaCO}_3$
  • D
    $\mathrm{NH}_4 \mathrm{NO}_3$

Solution

$\mathrm{CaCO}_3 \rightarrow \underset{\text { Basic }}{\mathrm{CaO}}+\underset{\text { Acidic }}{\mathrm{CO}_2}$

Hence, the correct answer is option: 'C'.
