Soda, Fun with pH testing??
Hey ladies, so I tend to have a little ocd and that is spilling into my sway! I found this website: http://biology.clc.uc.edu/scripts/phresl.pl with the results of pH testing of lots of things, including sodas. The lowest soda they list is Diet Rite, with a pH paper reading of 2.75 and meter reading of 1.75. But I think Diet Rite doesn't have aspartame. Here are the next, in order from lowest to highest according to their study (using paper reading):
Paper Reading Meter Reading
Regular Pepsi 2.88 3.33
Regular Coke 3.16 3.23
Pepsi, Caffeine free 3.50 2.82
Diet Pepsi 3.87 4.26
Coke, Caffeine free 4.00 4.40
Diet Coke 4.14 5.13
I would love to know the pH of Pepsi Max, since it is super low in sodium. Also it looks like regular soda has lower pH than diet. I would have thought it was the other way around. So my question is, we want diet though because of the aspartame right? So a diet pepsi with a meter reading of 4.26 would be better than a regular pepsi with meter reading of 3.33 because of aspartame?
By the way, milk registered kind of high, 6 - 7 pH. I was surprised by that.
