一般描述
Method: titrimetric with dropping bottle MQuant®
The Carbonate Hardness Test determines carbonate hardness as a measure of the buffering capacity of water which can also be expressed as acid-binding capacity or total alkalinity.
Carbonate hardness is a measure of the buffering capacity of water which can also be expressed as acid-binding capacity or total alkalinity. This MQuant® Carbonate Hardness test (formally MColortest®) is suitable for the titrimetric determination using a convenient dropping bottle.
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.
