Chemicals can be acidic, neutral or basic depending on how many hydrogen ions they have.

Hydrogen ions are really just protons, a small particle that has a positive charge.

This kit allows you to do revealing pH experiments such as testing for acid, testing for alkali, and making a salt substance.

Excellent for use as a science fair project or for classroom demonstrations!
