| Alkali in Emulsifier Solution |
| Log #114A Titration Application Note |
| Free alkalinity and soap content of an emulsifier solution were determined by titration with sulfuric acid. The titration has two endpoints: the first is equivalent to the free alkalinity (as %KOH), the second to the % soap. The % soap result is equivalent to the difference between the first and second endpoints. A different method is required for each endpoint because the first endpoint is much weaker than the second and because a different molecular weight is required for each result. |
