## Evolution Reactions
### Problem Statement
Write a molecular equation for the gas evolution reaction that occurs when you mix aqueous hydriodic acid and aqueous sodium sulfite.
**Express your answer as a chemical equation including phases.**
\[
2 \text{HI} (aq) + \text{Na}_2\text{SO}_3 (aq) \rightarrow 2 \text{NaI} (aq) + \text{H}_2\text{O} (l) + \text{SO}_2 (g)
\]
**Previous Answers**
### Solution Explanation
Correct
Begin by writing a skeletal equation that includes the reactants and products that form when the cation of each reactant combines with the anion of the other. Note that sulfurous acid decomposes to sulfur dioxide and water.
\[
2 \text{HI} (aq) + \text{Na}_2\text{SO}_3 (aq) \rightarrow \text{H}_2\text{O} (l) + \text{SO}_2 (g) + 2 \text{NaI} (aq)
\]
