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

Do you know volume of original Coca-cola and
Volume in which it is diluted?

First you know [H3O+] = 10^-pH.
Then you calculate concentration in a new
Solution.

Answer 2

Thank you for the questions. 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 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.
