Acids and Alkalis: Part 1

The properties of strong acids and alkalis can be extremely harmful. Where do we find them, and how can we tell how acidic or alkaline a substance is?

Chemistry - Reactions - Learning Points.

Bases neutralise acids, and if a base dissolves in water then the solution is an alkali.

Weak acids are safe to consume, but stronger acids can be harmful, irritant or corrosive.

Acids have a pH of less than 7 and alkalis have a pH greater than 7.

Universal Indicator solution can test any liquid to see how acidic or alkaline it is.
