**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. The image contains the following text, arranged in a question and answer format:---**Question:**"The purpose of the indicator is to determine when the end point of the reaction has occurred."**Options:**- True (selected)- False---This appears to be a multiple-choice question typically found in educational assessments about chemical reactions or titrations. There are no graphs or diagrams in the image. The selection indicates "True" as the chosen answer.

We need to find the effect of water on NaOH molarity. The student is weighed a flask into which the KHP weighted was wet. And them the function of indicator in titration. 1) Because KHP is moist, an error will occur during KHP weighing, resulting in a low KHP molarity, which will result in a low NaOH molarity when standardisation is performed. Therefore, the third choice is the correct response. That is too low. The NaOH solution is diluted by water. The given statement is True. The main function of indicator is to indicate the end point of titration.
