WebbIf pH >7, the solution is basic. The pOH should be looked in the perspective of OH-instead of H +. Whenever the value of pOH is less than 7, then it is considered basic. And … 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). film enchanted castWebbThe pH of an aqueous solution is based on the pH scale which typically ranges from 0 to 14 in water (although as discussed below this is not an a formal rule).
