Which of the following inorganic compounds liberate gas upon strong dry heating? — Qualitative and Quantitative Analysis Chemistry Question
Question
Which of the following inorganic compounds liberate $O_2$ gas upon strong dry heating?
Answer: A,B,C
💡 Solution & Explanation
$2AgNO_3 \rightarrow 2Ag + 2NO_2 + O_2$. $2Pb(NO_3)_2 \rightarrow 2PbO + 4NO_2 + O_2$. $2KClO_3 \rightarrow 2KCl + 3O_2$. However, $NH_4NO_2 \rightarrow N_2 + 2H_2O$, which releases $N_2$, not $O_2$.
