WebIt's somewhat contradictory to discuss pH as -log[H+], and then say that pH = -3.6 is possible. There is no way you can cram over 1000 moles of hydronium ions into a liter! The -3.6 value only makes sense if you explain that pH = - log (H+ activity), and that it is the deviation of activity from concentration that makes the value -3.6 possible. WebFeb 26, 2024 · Method 3: Soak the electrode in a 4.01 pH buffer solution, heated to 50oC for one hour. Allow the buffer to cool down to room temperature, then rinse the electrode with deionized or distilled water. This will open and clean the reference electrode. Method 4: After each use, rinse the electrode in 0.5 N or 1% HCl.
