What is pH in acids and bases?
The pH scale provides a way of measuring how acidic or basic solutions are. The scale ranges from 0-14. A pH of 0 is the most acidic, 7 is neutral and 14 is the most basic.
Here is a video of a lab which looks at a number of different solutions and measures their pH levels using a pH meter and an indicator.
