What is the pH of shampoo solution
Standardize the pH meter using a buffer solution of known pH value.Basically take buffer of pH value 4.Then set zero reading in the pH meter.Now remove unknown buffer solution.(take care with atmospheric temperature.)
The pH value of an acid solution depends on its concentration and the temperature of the solution.
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.
The nature of the solution be it acidic or basic will determine the PH value of the given solution.
This depends on the pH value of this solution !
A basic solution.
It color will became red from blue!
An acidic solution has a pH under 7 and a basic solution has a pH over 7.
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.
3,2,1 and zero, closer to the zero is more acidic solution.
The pH value for this solution is 13.
