Ph Lab Activity Page 3

Teacher Notes:

A = Coffee (acid)

B = Ammonia (base)

C = Diluted sodium hydroxide (base)

D = Diluted hydrochloric acid (acid)

E = Distilled water (neutral)

F = Lemon juice (acid)

G = Baking soda (base)

Each lab station should have a test tube holder filled with 7 test tubes labeled A-G.

Add a small amount of each unknown solution to the proper test tubes. Each group only needs about 5 drops of every

solution, so very little volume will be needed throughout the entire day.

The students will need to rinse their eyedropper in between every unknown solution to prevent contamination.
