What is the concentration of hydrogen ions in a solution that has a pH of 6.0?

1*10^6 M
1*10^-8 M
1*10^-6 M
1*10^-4 M

The correct answer is: 1*10^-6 M

A pH of 6.0 indicates an acidic solution, with a concentration of hydrogen ions of 1*10^-6 M. Option A, 1*10^6 M, is an extremely high concentration and would result in a very low pH, so it is not a correct answer. Option B, 1*10^-8 M, is a very low concentration and would result in a very high pH, so it is also not a correct answer. Option D, 1*10^-4 M, is closer to a neutral pH of 7, but still not the correct concentration for a pH of 6.0.
