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.
A strong acid, such as hydrochloric acid (HCl), has a pH of 1 and completely ionizes in aqueous solution, meaning all molecules dissociate into their constituent ions. This leads to a high concentration of hydrogen ions (H+) in the solution, resulting in the low pH value.
pH s calculated as the negative log10 of the hydrogen ion concentration. So log10 of 0.000724 = -3.14 so pH= 3.14
7, lower is acidic, higher is basic.
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.

Iodine does not have a pH since it is not an aqueous solution. pH is a measure of the concentration of hydrogen ions in a solution.
A 1.0 M aqueous solution has a pH of 11.6

The pH of a solution of C6H12O6 (glucose) is neutral at pH 7 since it does not directly contribute to H+ ions in solution.
Lithium chloride aqueous solution is neutral. It will not significantly alter the pH of the solution.
pH is the negative log of the activity of the hydrogen ion in an aqueous solution. A powder is not a solution.
pH is the negative log of the activity of the hydrogen ion in an aqueous solution. A powder is not a solution.
An aqueous solution of borax will have a slightly basic pH. Litmus is a pH indicator that turns blue in basic solutions and red in acidic solutions. Therefore, when litmus is added to an aqueous solution of borax, it will likely turn blue.
Nitrogen gas does not have a pH value because it is not an aqueous solution and does not produce ions in water to measure pH. pH is a measure of the concentration of hydrogen ions in a solution, which is not applicable to nitrogen gas.
