Acid Base Titration

An acid-base titration is the method of quantitative analysis for determining the concentration of an acid and base by exactly neutralizing it with a standard solution of base or acid having known concentration.

Question

**Titration of Weak Acid HY by NaOH**

Chaya, the chemistry student, carries out a titration by adding an aqueous solution of NaOH to an aqueous solution of the weak acid HY. The diagrams below represent the solutions at various stages during this titration. (Note: Na⁺ and H₂O are omitted for clarity.)

**Key:**
- HY (Purple)
- Y⁻ (Gray)
- H₃O⁺ (Red)
- OH⁻ (Brown)

**Diagrams:**

- **A:** Contains HY molecules only.
- **B:** Contains a mix of HY and H₃O⁺ molecules.
- **C:** Contains HY, Y⁻, and H₃O⁺ molecules.
- **D:** Contains HY, Y⁻, H₃O⁺, and OH⁻ molecules, indicating more products formed.
- **E:** Displays a greater quantity of Y⁻ and OH⁻ molecules, with some HY still present.

**Instructions:**

Select the image corresponding to each of the following points in Chaya's titration:

1. **Before adding any NaOH:**
2. **Partway to the equivalence point:**
3. **At the equivalence point:**
4. **After the equivalence point:**

Each of these stages shows the progression of the titration process, from the initial acid solution to beyond the neutralization point where excess base is present.
