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. MethodHydrogen 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 Surface water, seawater Drinking water and mineral water (after degassing) Aquarium water, waters from aquaculture Industrial water, process water Boiler and boiler feed water, cooling water
