When baking soda (sodium bicarbonate, NaHCO₃) is mixed with acetic acid (HC₂H₃O₂), they undergo an acid-base reaction, producing carbon dioxide (CO₂), water (H₂O), and sodium acetate (NaC₂H₃O₂).
The balanced chemical equation for the reaction is:
\[ \text{NaHCO}_3 (s) + \text{HC}_2\text{H}_3\text{O}_2 (aq) \rightarrow \text{CO}_2 (g) + \text{H}_2\text{O} (l) + \text{NaC}_2\text{H}_3\text{O}_2 (aq) \]
Here are some correct statements about this reaction:
1. **Gas Production**: The reaction produces carbon dioxide gas, which can be observed as bubbles or fizzing during the reaction.
2. **Neutralization Reaction**: The reaction is a type of neutralization where an acid reacts with a bicarbonate to produce a salt, water, and carbon dioxide.
3. **Endothermic Reaction**: The reaction is slightly endothermic, which means it can absorb heat from its surroundings, leading to a slight decrease in temperature.
4. **Change in pH**: The acetic acid (acid) neutralizes the baking soda (basic), affecting the pH of the solution.
