10.  Label as either true (T) or false (F):  _____ 4.Acids turn red litmus paper blue.

11.  Label as either true (T) or false (F):  _____ 5.Acids react with some metals to produce hydrogen gas.

12.  Label as either true (T) or false (F):  _____ 6.Acids will turn litmus paper indicator pink/red.

13.  Label as either true (T) or false (F):  _____ 7.An indicator is a substance which changes colors in acids and bases.

14.  Label as either true (T) or false (F):  _____ 8.Bases turn blue litmus paper red.

15.  Label as either true (T) or false (F):  _____ 9.Bases feel slippery.

16.  Label as either true (T) or false (F):  _____ 10.The pH of water is 7.

17.  How might the burning of coal in one area of the country affect the environment in another area? (Think acid rain)

18.  How can an acid be neutralized?

19.  The pH of a strong base would be closest to? _______________________

20.  The pH of a strong acid would be closest to? ________________________

21.  True or False: A compound that shows a color change when mixed with an acid or base is called a conductor.

22.  As the pH number of an acid decreases, the strength of the acid _____________________.

23.  How does acid rain form? What are steps we can take to solve this problem?

24.  Another word for "basic" is  A.styrene.  B.alkaline.  C.heavy.  D.strong.

25.  Why is acid rain a problem?  A. It is harming our drinking water and water supply companies are suffering  B. It causes harm to aquatic life, soil, plants, buildings, statues, humans, and more  C. It is only a problem if you live near a factory  D. It can cause fish to reproduce too quickly, creating an imbalance in the food chain

26.  Why is water and soil around Ohio less acidic than the actual rain?  a) Rain water moves through the ground which contains limestone bases which help neutralize the acids.  b) As animals drink the water, it becomes basic  c) When the sun warms the water it evaporates all of the acid out of it.  d) Flowers and plants can only survive if the water is basic, so they have mechanisms in their  roots to change the pH of the water.
