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.
Sodium hydroxide is an alkali; the pH of the solution is over 7.
The correct formula is NH4Cl. This compound can be found both as a solid and in an aqueous solution.
- log(0.001 M NH4Cl) = 3 pH =====
NH4Cl can exist as both a solid or as an aqueous solution. In its solid form, NH4Cl is a white crystalline compound, while in its aqueous form it dissociates into ammonium ions (NH4+) and chloride ions (Cl-) in water.
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
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.
