Question
**Question:**

Would the calculated value of the molarity of the NaOH solution be too high or too low or unchanged if the flask into which the student weighed the KHP was wet?

**Options:**

- Unchanged. The NaOH concentration wouldn't be affected by the amount of water.
  
- Too high. The NaOH solution is diluted by the water.
  
- Too low. The NaOH solution is diluted by the water. (Selected)

**Explanation:**

When weighing KHP (potassium hydrogen phthalate) in a wet flask, the presence of additional water leads to a dilution of the NaOH solution. This causes the concentration of the NaOH to be lower than expected, resulting in a calculated molarity value that is too low.
