- Estimated study time: 30 minutes
Study resources
- Hardness of Water by EDTA Method - Lecture 9 (numericals) (Video) — Continuation of the previous lecture with solved numerical problems. Do these along with the video rather than just watching.
- Hardness of Water - types, causes, removal and solved calculation (Vedantu) (Article) — Gives the standard formula (V x M x 1000 / sample volume) with a worked example and the IS 10500 Indian drinking-water limit of 200 mg/L.
- Hardness of Water by EDTA Method - Lec 8 (Video) — Part 1 of a numerical-focused series for B.Tech 1st year. Sets up the formula and units (ppm, mg/L, degrees Clark, degrees French).
- Hard Water - Wikipedia (Article) — Types of hardness (temporary and permanent), causes, units of hardness and effects. Read this before any softening method.
- Numericals on Zeolite & Lime-Soda Softening (Video) — Curated YouTube search for solved numerical problems on softening capacity and quantity of chemicals required.
