The 'Doc' has been busy this week!

Dr. Sam Rowe has been busy this week filming with Paul. In this lesson, the 'Doc' sets a challenge which explores the pH of a variety of substances. 

Did you know that mixing acids and bases can cancel out, or neutralise, their extreme effects? The pH scale ranges from 0 to 14 and gives an indication of how acidic or basic something is. A substance that is neither acidic nor basic is neutral.
