The new Cabbagindicator!
A new indicator! For kids!
How does it work?
An acidic solution contains an excess of protons or H+. pH is a measure of how 'acidic' a solution is. The lower the pH, the more acidic the solution. In chemical terms, pH means "the negative log of the concentration of protons" in solution.
- Use substances that you are sure of its pH.
- Don't forget the safety procedures, use safety glasses.
- It would save more time, if you already have the red cabbage juice, before the experiment. So just buy the Cabbagindicator! It's cheap and already in the liquid form!
