Homework 1 1/19/11

Use the pH paper to develop a table and graph o the pH of common things around your home.

Think in terms of at least 10 different liquids. 

1. Water = pH 5

2. Vodka = pH 6

3. Diet Mtn Dew = pH 5

4. Orange Juice = pH 6 (barely visable)

5. Beer = pH 6

6. Hair spray = 6 (it was lighter than all of the rest of them)

7. Bleach = pH 6
8. Windex = pH 9

9. Oil =pH 4

10. Tide = pH 8




Develop an experiment to see how much antacid is needed to neutralize an acidic liquid. 

I took Oil and put 1/4 of a tums into one container, and 1 tums into another.  Both became lighter, but the one tums seemed to be a little clearer.  It was not as orange it was more like the color of the pH paper to begin with.
