How much NaOH is needed to prepare 576 mL of solution with a pH 10?
Is the concentration of a solution the same as the concentration of [OH-] or [H+]?
No it is not. The fixed pH solutions only work with weak acids or bases and their conjugate salts.
pH ten means the -log of the activity of the hydrogen ion against a standard calomel electrode is 10.
Even electrodes are standardized against buffer solutions.
This also means the concentration of hydrogen ion is at 10^(-10) M for this solution. The hydroxide concentration would have to be at 14-10 =4 =pOH or 10^(-4) M
That is ...
