- For
- Arabic-speaking water-analysis learners and trainees
- Worth noticing
- The hardness course lists six lessons and ten questions; chloride lists eight lessons and ten questions, with a simulation for each.
Field notes
The Arabic-language interface organizes the material as courses, with lesson and quiz counts shown before entry. The hardness course covers EDTA titration and calcium-carbonate-equivalent calculations; the chloride course describes silver nitrate titration and a blank correction. The homepage lists five additional water-chemistry topics as coming soon, rather than presenting them as available courses.
