Transcribed Image Text:1. **Reaction:**
- \( \text{H}^+ + \text{LiOH} \rightarrow \)
- Result: \( \text{Li}^+ + \text{H}_2\text{O} \)
2. **Reaction:**
- \( \text{H}^+ + \text{CHO}_2^- + \text{Li}^+ + \text{OH}^- \rightarrow \)
- Result: \( \text{Li}^+ + \text{CHO}_2^- + \text{H}_2\text{O} \)
3. **Reaction:**
- \( \text{HCHO}_2 + \text{OH}^- \rightarrow \)
- Result: \( \text{CHO}_2^- + \text{H}_2\text{O} \)
4. **Reaction:**
- \( \text{H}^+ + \text{OH}^- \rightarrow \)
- Result: \( \text{H}_2\text{O} \)
5. **Reaction:**
- \( \text{Li}^+ + \text{CHO}_2^- \rightarrow \)
- Result: \( \text{LiCHO}_2 \)
Each reaction step demonstrates different chemical processes, showing ion interactions and resulting compounds.

Transcribed Image Text:**Question:** What is the net ionic equation for the neutralization reaction that occurs between HCHO₂ (aq) and KOH (aq)?
**Explanation:** In the context of chemistry, a net ionic equation simplifies the equation for a reaction by showing only the species that actually change during the reaction. With a neutralization reaction like the one between formic acid (HCHO₂) and potassium hydroxide (KOH), the key event is the reaction between hydrogen ions (H⁺) from the acid and hydroxide ions (OH⁻) from the base to form water (H₂O). The other ions present in the solution do not participate directly in the reaction and are omitted from the net ionic equation.
**Graph/Diagram Explanation:** There are no graphs or diagrams in the image. If included, a diagram might display ions before and after the reaction, emphasizing how H⁺ and OH⁻ form water, and how K⁺ and CHO₂⁻ remain in the solution unchanged.
