Homework 1-19-11

Use the pH paper to develop a table and graph of the pH of common things around your home. (10+ liquids)

Liquid	pH
Tap Water	7
Tequila	6
Rum	5
Vodka	5
Orange Juice from Concentrate	3
Brita Filtered Water	6.5
Chocolate Milk	6.5
2% Milk	6.5
Saliva	8
Saliva #2	7

Develop and experiment to see how much antacid is needed to neutralize an acidic liquid. (with 1 liquid)

I did mine with my orange juice from concentrate because that is the most acidic liquid I have. It has a pH of 3 and you can see from the graph below that as I added tums the pH got more base, but stopped at around 6.

I could not get excel to graph this and my SPSS wouldn't work, maybe because I got a loaner computer, but so I made it in Paint. pH is on the x-axis and the amount of calcium carbonate is on the y-axis. You can see where it hit a ceiling affect at 6 pH, which must be close to the pH of tums.
