How to Measure Water Hardness | Pelican Water
How to Measure Water Hardness | Pelican Water

If a ,test, for hard water is measured in parts per million or milligrams per liter you can take the ,total hardness, level and divide it by 17.1 to get ,hardness, in grains per gallon. For example if your water ,test, shows 250 mg/L ,hardness, you actually have 14.62 grains per gallon.

Determination of Hardness of Water by EDTA Titration method
Determination of Hardness of Water by EDTA Titration method

Procedure for calculation of hardness of water by EDTA titration. Take a sample volume of 20ml (V ml). Dilute 20ml of the sample in Erlenmeyer flask to 40ml by adding 20ml of distilled water. Add 1 mL of ammonia buffer to bring the pH to 10±0.1. Add 1 or 2 drops of the indicator solution. If there is Ca or Mg hardness the solution turns wine red.
