WebSep 30, 2024 · The numbers of the pH scale come from a formula for the hydrogen ion (H +) concentration. The equation for pH is: pH = -log [H +] The way a logarithmic scale works, chemicals that donate more hydrogen ions (protons) have lower pH values. These are acids. Chemicals that accept hydrogen ions have higher pH values and are bases. Web2. Test the pH of the diluted sample using pH strips or pH meter. 3. If the pH of the diluted sample is out of the recommended range of the 3M Petrifilm Plate, add increments of either 1 N sodium hydroxide (NaOH) (for acidic samples) or 1 N hydrochloric acid (HCl) (for basic samples) until the pH is within the recommended range.
