Question:
Two of the products formed by the reaction of \(X\) with HCl are gases. What is \(X\)?
HCl with \(X\) forms gaseous products, two of which are identified.
Two of the products formed by the reaction of \(X\) with HCl are gases. What is \(X\)?
HCl with \(X\) forms gaseous products, two of which are identified.
Show Hint
When reacting metal nitrites with HCl, typically gases such as NO and NO\(_2\) are formed.
Remember that these reactions often release nitrogen oxides.

The Correct Option is A
Solution and Explanation
When sodium nitrite (NaNO\(_2\)) reacts with hydrochloric acid (HCl), it produces nitrogen dioxide (NO\(_2\)) and nitrous acid (HNO\(_2\)). Nitrogen dioxide is a gas and the other product, nitrous acid, is unstable and decomposes to form more nitrogen dioxide and water. This reaction can be represented as:
\[
2 \, \text{NaNO}_2 + 2 \, \text{HCl} \rightarrow 2 \, \text{NaCl} + \text{NO}_2 (g) + \text{H}_2\text{O} + \text{NO} (g)
\]
Therefore, the two gaseous products formed are \( \text{NO}_2 \) and \( \text{NO} \), confirming that \( X \) is NaNO\(_2\).
