- I made a graph of my information and I'm not sure how to save it and put it on the blog so hopefully this website works. If it doesn't, I can email you the actual graph because it's in pdf form.
For this activity, I did 11 different types of things around my dorm room and measured it's acidicy. I found that most of them were around 5, 6 and 7. I did have one question though and that was if something is dyed a certain color, does that affect me testing its acidicy on the paper I recieved? Just something to think about but other than that it was an interesting little assignment. My graph shows my results.
Develop an experiment to see how much antacid is needed to neutralize an acidic liquid.
| [H+] | pH | Example | |
| Acids | 1 X 100 | 0 | HCl |
| 1 x 10-1 | 1 | Stomach acid | |
| 1 x 10-2 | 2 | Lemon juice | |
| 1 x 10-3 | 3 | Vinegar | |
| 1 x 10-4 | 4 | Soda | |
| 1 x 10-5 | 5 | Rainwater | |
| 1 x 10-6 | 6 | Milk | |
| Neutral | 1 x 10-7 | 7 | Pure water |
| Bases | 1 x 10-8 | 8 | Egg whites |
| 1 x 10-9 | 9 | Baking soda | |
| 1 x 10-10 | 10 | Tums® antacid | |
| 1 x 10-11 | 11 | Ammonia | |
| 1 x 10-12 | 12 | Mineral lime - Ca(OH)2 | |
| 1 x 10-13 | 13 | Drano® | |
| 1 x 10-14 | 14 | NaOH |
By looking at this graph you can see that Tums are below neutral so it's negative 10. Now when someone takes tums you are only supposed to take 2 to 4 at one time so if someone were to swallow lemon juice on accident, they should take two tums if they're stomach is upset. This is an estimate- I am not actually sure how you would calulate it but I think this graph is a good beginning.
