WebThe hydrogen ion concentration decreases by a factor of 10, so the pH increases by 1 from 1.6 to 2.6. Question A solution of hydrochloric acid, with a concentration of 2 g/dm 3 , has a pH of 1.3. WebTo 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).
