Solid Precipitate Experiment

• First we added 6 drops of ammonia (NH3) into a 10ml solution of water (H20) and copper sulfate (H10CuO9S).
• A white precipitate will form.
• As you add more ammonia ( in 6 drop increments) more precipitate will form.
• As more precipitate formed and fell to the bottom of the tube; the precipitate seemed to be yellow-green in color.

3 of the 4 signs of chemical reactions occurred in this experiment.

• Color change
• Energy being given off
• Formation of a precipitate
