WebbTo calculate pH, you should know the concentration of hydrogen ions (H +) in your solution. From there, the pH can be found by: p H = − log 10 ( [ H +]) Since this is a logarithmic calculation, in order to change the pH by one unit (say, from 2 to 3), the concentration of H + must be changed by 10 times (say, from 0.01 mol/L to 0.001 mol/L).

Webb10 feb. 2014 · Our happy water molecule. When water is in a pure or distilled state, it measures a pH of 7. The lower the number (0-7), the more acidic it’s considered. And the higher the number (7 to 14), the more basic it is. The pH scale may seem small, but each whole number represents a ten-fold leap in concentration of either H ions or OH ions. sharon yocumWebb9 juli 2014 · You will use the following equation to find the pH. pH = -log [H+] This means you take the negative log of the hydrogen ion concentration to find the pH.
