Diet Coke has a pH of about 3.0. Milk has a pH of about 7.0. How much greater is the H+ ion concentration of Diet Coke when compared to milk?

Question

- Would it be 1x10^4 greater concentration

Answer 1

Yes, 7-3=4 and each unit on the pH scale, since it is a log scale, is equal to 10; therefore, the coke is 10^4 times more acidic and that is 10,000 times.
