No. pH is a log scale. You can't have a pH of zero. ---- Above answer left in to correct a misconception. Yes, you certainly can have a pH of zero. A 1 molar solution of a strong acid has a pH of zero, and stock HCl (roughly 12 molar) has a pH of about -1.1 or so. pH is the negative log of the hydrogen/hydronium ion concentration, which for a strong acid is approximately the same as the acid concentration. The log of 1 is zero, therefore the pH of a 1 molar solution of a strong acid is zero. The log of 10 is 1, therefore the pH of a 10 molar solution of a strong acid is -1.

pH is the negative log of the activity of the hydrogen ion in an aqueous solution. A powder is not a solution.

In an aqueous solution, the concentration of H3O+ is the same as the concentration of H+. If you know the pH of the solution, then that's equal to 10^(-pH).
The solution is neutral.
That is correct, only an aqueous solution has a pH value. There are certainly chemicals in either a solid or gaseous state which will have an effect on the pH of an aqueous solution if they dissolve in that solution, but until they do, they do not have a pH.
No, the bases increase the pH of an aqueous solution.
Dry hair has no pH. Only aqueous solutions have pH's. When hair is in an aqueous solution it normally has a pH of 4.5 to 5.5
No. The pH scale is a measure of acid in aqueous solutions, meaning that the solution needs to be mostly water. Since oil has nearly zero water, the pH scale is irrelevant.

Any aqueous solution that has a pH value greater than 7 can be considered alkaline. A strongly alkaline aqueous solution usually has a pH of at least 10, and aqueous solutions of very strong alkalies can have a pH range above 13.
A 1.0 M aqueous solution has a pH of 11.6

yes, pH can be measured in a water (an aqueous) solution.
