Hello Sir! Thank you very much for these helpful videos. I am currently attempting this titration following the ISO 14184-1:2011. I was hoping you could possibly share the name of the paper where you find this method. The ISO I followed was almost exactly the same as what you showed in the video except for it requiring thymolphthalein indicator (10 g/L in ethanol) rather than phenolphathalein (10 ml/L). Thank you again for the great videos!
