Study Notes
Water Filtration Experiment
- Materials Used: Plastic water bottle, coffee filter, charcoal packet, pebbles, sand.
- Initial Water Condition: Extremely dirty water, containing dirt, soil, pebbles, fish tank debris, and exhibiting a green/blue tint. Initial pH of 5 (acidic).
- Filtration Process: Dirty water was poured through the layered filter. Large debris was trapped by pebbles and sand, and impurities were absorbed by charcoal.
- Filtered Water Observation: The filtered water was noticeably clearer but still had a slight murky appearance and a faint green tint. It was significantly cleaner than the initial water.
- pH Adjustment: pH of filtered water was measured at 5, indicating acidic conditions. Baking soda was added to raise the pH to 7 (neutral).
- Results Conclusion: The simple filter effectively removed visible impurities from the dirty water, resulting in cleaner water. Adding baking soda successfully neutralized the water's acidity.
