Current Question (ID: 10628)

Question:

$\text{By heating which of the following, would } \text{NO}_2 \text{ be produced?}$

Options:

1. $\text{NaNO}_3$
2. $\text{AgNO}_3$ (Correct)
3. $\text{NH}_4\text{NO}_3$
4. $\text{NH}_4\text{NO}_2$

Solution:

$\text{Hint: Ammonium nitrate produce } \text{NO}_2$$ $\text{The reactions of the given compounds in the options are as follows:}$ $\text{AgNO}_3 \text{ has a covalent character and these types of compounds are thermally unstable.}$ $2. \text{AgNO}_3 \rightarrow \text{Ag} + \frac{1}{2}\text{O}_2 + \text{NO}_2$ $2\text{NaNO}_3 \xrightarrow{500°\text{C}} 2\text{NaNO}_2 + \text{O}_2$ $4\text{NaNO}_3 \xrightarrow{800°\text{C}} 2\text{Na}_2\text{O} + 5\text{O}_2 + 2\text{N}_2$ $\text{NH}_4\text{NO}_2\text{(s)} \rightarrow 2\text{H}_2\text{O}\text{(g)} + \text{N}_2\text{(g)}$ $\text{NH}_4\text{NO}_3 = \text{N}_2\text{O} + 2\text{H}_2\text{O}$ $\text{Hence, answer is option second.}$
