General description
The MQuant® Carbonate Hardness test (formally MColortest®) uses a graduated syringe to determine carbonate hardness as a measure of the buffering capacity of water which can also be expressed as acid-binding capacity or total alkalinity.
Method
Hydrogen carbonate and carbonate ions are titrated with hydrochloric acid against a mixed indicator. At the titration end-point (at pH 4.3) the color changes to red. The carbonate hardness (acid capacity) is determined from the consumption of titration solution.
This test can be used in
