SM 2340C EDTA Standard Test for Titrimetric Method

EUROLAB laboratory provides testing and compliance services within the scope of the SM 2340C standard. This method determines the hardness of a water sample.

Initially, water hardness was understood as a measure of the soap-precipitating capacity of water. Soap is precipitated mainly by the calcium and magnesium ions present.

Other polyvalent cations may also precipitate soap, but these are often in complex forms with organic compounds and their role in water hardness is minimal and can be difficult to identify.

In accordance with current practice, total hardness is defined as the sum of the concentrations of calcium and magnesium in milligrams per liter, both expressed as calcium carbonate.

When the hardness is numerically greater than the sum of the carbonate and bicarbonate alkalinity, this amount of hardness equivalent to the total alkalinity is called carbonate hardness; The amount of hardness that exceeds this is called non-carbonate hardness.

When the hardness is numerically equal to or less than the sum of carbonate and bicarbonate alkalinity, all hardness is carbonate hardness and no non-carbonate hardness. Depending on the source and treatment to which the water is exposed, hardness can range from zero to hundreds of milligrams per liter.
