An acid is a chemical dissolved in water that has a pH less than 7.

Acids can be an Irritant, Harmful or Corrosive and should be handled with care.

When an acid is dissolved in solution the Hydrogen atoms in the molecule become free to move around and these are what make it an acid.

Acids can be weak or strong which depends on the type of acid and the concentration.

Acids turn Litmus paper red.

Acids turn Universal Indicator pink, red, orange or yellow depending on the strength of the acid.
