Webb26 apr. 2024 · If the pH is lower than desired, adjust it using sodium hydroxide solution. Fill a plastic pipette with the correct solution, add a few drops to the solution in the beaker and wait at least 20 seconds before reading the pH on the meter. If you need to adjust the pH further, add more of the solution until you achieve the desired pH. Webb2 maj 2024 · How to Calculate pH and [H+] The equilibrium equation yields the following formula for pH: pH = -log 10 [H +] [H +] = 10 -pH. In other words, pH is the negative log of …
