how many different types of indicators are there?

Erichrome Black-T is only used for testing water hardness. Methyl Orange is used for Weak Base/Strong Acid tests. Phenolphtalian is only used for the vinegar experiment which is a Strong Base/Weak Acid experiment. Starch indicator is used whenever iodine is involved.
