If soap has a high alkali content,it irritates the skin. How can the amount of excess alkali be determined? What can be the source of excess alkali?
(N/A) The amount of excess alkali in soap can be determined by performing an acid-base titration using a standard acid solution with a suitable indicator.
The source of excess alkali is typically the unreacted $NaOH$ or $KOH$ that remains in the soap mixture after the saponification process (hydrolysis of fat/oil) is complete.
