Acids & Bases

Acids:

Characteristics:

-taste sour

-have a pH of less than 7

-are electrolytes

-react with active metals to produce hydrogen


Examples:

-Sulfuric Acid (H2SO4)

-Nitric Acid (HNO3)

-Hydrobromic Acid (HBr)


pH:

-The pH of an acids range from 0 to 7


Strong and Weak Acids:

-Sulfuric acid is a strong acid which has a pH of .3

-Hypochlorous acid is a weak acid which has a pH of 6.5

Bases:

Characteristics:

-taste bitter

-feel slippery

-have a pH greater than 7

-are electrolytes

-neutralize acids producing salt and water


Examples:

-Lithium hydroxide (LiOH)

-Sodium hydroxide (NaOH)

-Potassium hydroxide (KOH)


pH:

-The pH of bases range from 7 to 14


Strong and Weak Bases:

-Lithium hydroxide is a strong base.

-Ammonia is an example of a weak base.

What does it mean to have a pH of 7?

Having a pH of 7 means that the acids/bases are neutral.
