Question
Which of the carbonates does not decompose to give carbon dioxide?
Hint:
Carbonates of sodium and potassium are stable.
The correct answer is:
Usually the carbonates decompose when heated to give the metal oxide and carbon dioxide. Carbonates of sodium and potassium are stable and they do not decompose on heating. So, the carbonates that do not decompose on heating are do not produce on heating.
Na2CO3 and K2CO3 are stable carbonates and thus do not decompose on heating.
Na2CO3 and K2CO3 are stable carbonates and thus do not decompose on heating.
