Online calculator: pH of a solution calculator
A solution of a strong alkali at concentration 1 M (1 mol/L) has a pH of 14. Thus, in most problems that arise pH values lie mostly in the range 0 to 14, though negative pH values and values above 14 are entirely possible. Weak acid/base. Weak acids/bases only partially dissociate in water. Finding the pH of a weak acid is a bit more complicated.
How can I calculate pH of NaOH? | Socratic
You can calculate pH if you know the concentration of the NaOH. You will need to know the molarity of the NaOH. Let's assume the solution is 0.1M. NaOH is a strong base, so this will produce 0.1mol/L of OH ions in solution. This will produce a pH of 13. You will need to take the negative log of 0.1 to find the pOH. This will work out to be 1. Since …
