How do you go about calculating concentration from ph?

Answer by  davidsait (27)

pH=-log10[H+]. Concentration of H+ ions is found by taking the anti-log. [h+] = 10^-ph. If using a calculator, put in -pH, then hit the 10^x button (which is probably shift and the log10 button).

The concentration of hydrogen ions is found by taking the inverse log (base 10) of the negative of the pH. So, if the pH is 3.5, [h+] = 10^-3.5 = 0.00032 m. Concentration unit is molarity.

The ph of a substance is equal to the log (base 10) of the concentration of H+ ions. Therefore concentration would equal 10 to the power of ph.
