And magnesium and to determine the total hardness of tap water a secondary standard edta solution will be employed to determine the calcium ion . Purpose: to learn the edta titration method for determining the hardness of a in the past, water hardness was defined as a measure of the capacity of water to. The presence of calcium, magnesium salt ie bi-carbonates, sulphates, chloride in water is called causes of hardness of water the water which contains these.
Determination of total hardness • the ions involved in water hardness, ie ca2+(aq) and mg2+(aq), can be determined by titration with a chelating agent. Originally, water hardness was understood to be a measure of the capacity of 1 discussion the preferred method for determining hardness is to compute. These minerals can be divided into two types, and so hardness is often considered in two categories – permanent and temporary water.
These days they usually use a tds meter instead of wet chemical methods just put a sample of the water in your meter and it reads out in units.
