Question:medium
Which of the following gives more number of oxides on reacting with $\text{HCl}$?
Which of the following gives more number of oxides on reacting with $\text{HCl}$?
Show Hint
Salts of weak, volatile acids (like carbonates, sulfites, and nitrites) react with strong, non-volatile acids (like $\text{HCl}$) to produce the corresponding oxide of the weak acid upon decomposition. Nitrous acid ($\text{HNO}_2$) is notoriously unstable and decomposes into a mix of nitrogen oxides.
