How to Prepare a Sodium Hydroxide or NaOH Solution - ThoughtCo

WebSodium hydroxide is a white hygroscopic solid and is one of the strongest bases. In water it dissolves very well under great heat generation due to the negative enthalpy of solution of -44.4 kJ/mol to the strongly alkaline reacting sodium hydroxide solution (pH 14 at c = 1 mol/L). It is always completely dissociated in aqueous solution. Web3. Place the electrode in pH 10 buffer (which is blue) and swirl it around in the solution. 4. Set the pH meter to pH 10 and rinse the electrode, returning it to the distilled water once you are finished. The pH meter should now be calibrated to measure any pH accurately. Standardizing a Sodium Hydroxide (NaOH) Solution 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.
