### Determining the \( K_a \) for a Weak Acid

**Instructions: Fill in the blanks to complete the statements on how \( K_a \) for the weak acid will be determined.**

The **equivalence** point will be determined directly from the volume of sodium hydroxide solution at the **half-equivalence** point. This will be calculated by dividing the **strong base** volume by two. The pH at the half-equivalence point is equal to the \( pK_a \) of the **weak acid**, and is read directly from the **printed graph**. \( K_a = 10^{-pK_a} \).

#### Answer Bank:
- equivalence
- molarity
- strong base
- printed graph
- \( -pK_a \)
- half-equivalence
- weak acid
- volume
- \( pK_a \)
- literature

**Diagram Explanation:**

The diagram is a fill-in-the-blank exercise structured with an instructional statement followed by selectable answers in the "Answer Bank." The goal is to construct a sentence that accurately describes the process of determining the \( K_a \) for a weak acid.
