Question
I'm very confused on how to do these
**Diazepam, a sedative, \( pK_a = 3.40 \)**
---
### Problem Overview
**Objective:** Determine whether the acid or conjugate base form of diazepam predominates at the following pH values: 2.75, 3.40, and 6.75. For each pH value, determine if the given form is charged or uncharged.
**Instructions:** Drag the appropriate items (acid, conjugate base, charged, uncharged, both forms in equal amounts, not applicable) into their respective bins corresponding to each pH value.
### Available Options
- **Both forms in equal amounts**
- **Charged**
- **Acid**
- **Conjugate Base**
- **Not Applicable**
- **Uncharged**
### pH Bins to Fill
- **pH = 2.75**
- **pH = 3.40**
- **pH = 6.75**
---
**Submit your answer once you have made your selections.**
Remember to consider the \( pK_a \) and pH relationship to determine the dominant form and its charge.
