## Activity Report: pH Measurements in Different Water Samples

## Objective

To measure and compare the pH levels of different water samples, understanding their acidic or basic nature.

## Materials

- pH paper or pH meter

- Water samples from various sources (tap water, groundwater, RO water, etc.)

## Procedure

1. Collected water samples from different sources.

2. Calibrated the pH meter or used pH paper to ensure accurate readings.

3. Measured the pH of each water sample.

4. Recorded the pH values and observed any notable characteristics.

## Results

Water Sample pH Value Nature

Tap Water 6.8-7.2 Neutral

Groundwater 7.0-7.5 Neutral to Slightly Basic

RO Water 6.5-7.0 Slightly Acidic to Neutral

## Discussion

The pH measurements revealed variations in the acidity or basicity of different water samples. Understanding these differences is crucial for ensuring water quality and safety.

## Conclusion

This activity demonstrated the importance of pH measurement in water quality assessment. By analyzing pH levels, we can better understand the characteristics of different water sources and take necessary steps to ensure their safety for consumption.

## Recommendations

- Regular pH monitoring of water sources to ensure consistency and safety.

- Adjustment of pH levels in water treatment processes to meet drinking water standards.

- Further investigation into the causes of pH variations in different water sources.

This activity provided valuable insights into the pH levels of different water samples, highlighting the significance of pH measurement in water quality management.
