pH Scale & Indicators
pH Scale:

The pH scale is used to determine whether a substance is either acidic or basic. We want to find this information because it is important in determining if the substance can be applied to something. To find this out, you must add drops of Universal Indicator to the substance.
The pH scale has different colours and numbers to indicate this; the scale runs from 1 - 14.
However, the acids are from 1.0 - 6.9 (Pink - Yellow).

Litmus paper also helps to indicate acids and bases. The special paper turns either blue or red depending if it is an acid or a base. Blue for a base, red for an acid.
