by Mary Pat Scientists identify acids and bases by using the pH scale.
The pH scale shows the amount of acid or base in a substance. Scientists read the pH by
what color the pH paper turned after it was dipped in the solution. If it's a 6 or lower,
then it's considered an acid, if it's a seven, it's a neutral, or if it's an 8 or higher,
then it's a base. |
by Michael Acid rain is rain with a lot of acid in the
rainwater, with a pH under 6. A pH over 6 is regular rain. Acid forms from the fossil
fuels from cars, airplanes, and factories. It also forms from the exhaust from the cars,
airplanes, and factories. |
by Tamika An acid is a source that turns pink with cabbage juice. A
base is a source that turns green with cabbage juice. All these sources turn a certain
color when cabbage juice is added to them. Lemon juice and vinegar both turn yellow with
the pH paper. Baking soda turns brown with pH paper. There is a scale called the pH scale
that will tell how strong acids, bases, and neutrals are. The number on the pH scale will
make it a lot easier for you to read because sometimes cabbage juice is not accurate. |
by Mary Pat Acid rain affects plants, animals, and people. It affects them all differently, too. It takes away the color from plants and then kills them. With animals, it can pollute their natural habitats like how it can pollute the water where the fish live. If there's too much acid in the water, then it can suffocate the fish. It affects people by poisoning them, and could kill them. Return to Class Projects |
