Question

what pH is pH 2.6 minus pH 3.0

essentially I need to find out what the pH of Coca Cola (pH 2.6) would be if it were bottled with Still water at pH 7 rather than carbonated water at pH 3...

Answer 1

you can use the log definition of ph

Answer 2

hey welcome to open study...

please your question in the relevant section, so that it may be solved/guided properly...

thanks...

Answer 3

thought this was a math question above all else... forgive me, which section do you suggest?

Answer 4

Science lol

Answer 5

Chemistry I guess

Answer 6

no chemistry.... it's related to chemistry....

Answer 7

pH is a mathematical function no? i do not know how to best solve it and chemistry forum brings no takers. (sigh) where might i best go to have this solved if not here or there?

Answer 8

PH=-log[H+] concentration. Your ? is not worded clearly.

Answer 9

7-3=4

Answer 10

@perl can take her from here.

Answer 11

@AmTran_Bus I thought you were majoring in chemistry

Answer 12

thanks for noting limitations in the question. does this help:
Volume doesn't matter. Lets say one liter. One liter of regular soda Coca Cola with pH 2.6 made with carbonated water. and then 1 liter containing same flavoring formulation in a neutral pH of still water.
I need to find the ph value of the flavor components without taking into the account the pH of the carbonated water itself, which i understand to be around 3.0.

Answer 13

I know it can't be a straight up a-b=c.
pH is a logarithmic value and each number represent 10x more than previous. I just don't know how to calculate it, regrettably even if given proper formula... too many years out of school. But I still need to know the answer.
Would anyone be so kind as to help answer?

Answer 14

regrettably i cannot answer this, but i think khan academy has the answer
