Acids Affect Indicators:

Blue litmus paper turns red in contact with an acid.

Bases affect indicators:

Red litmus paper turns blue in contact

with a base. Phenolphthalein turns pink in a

base.

Molarity

• Molarity= moles of a substance/liter water

• Molarity= M

• Ex. 18M Sulfuric acid means that there are 18 moles of sulfuric acid per one liter of water

• Molarity deals with liquid solutions
