Conduct chemistry experiments focused on pH. Extract natural pH indicators from red cabbage, beets, or turmeric. Test common household substances and see color changes. Create acid-base reactions that fizz, foam, and transform. Measure pH of substances from lemon juice to drain cleaner. Build understanding of chemistry fundamentals through colorful, safe, and tangible experiments. Every reaction visible and measurable.
Jak zacząć
- 1Boil red cabbage in water to create natural pH indicator
- 2Strain the purple liquid (indicator solution)
- 3Collect samples of household liquids: lemon juice, baking soda solution, soap, vinegar
- 4Add indicator solution to each sample and observe color changes
- 5Create a pH scale reference chart from your observations
- 6Test new substances and predict their pH based on color

Ciekawostka
pH scale goes from 0 to 14, but substances beyond this range exist—extremely strong acids and bases go negative or above 14.
