General description
Method: titrimetric with dropping bottle MColortest®
The test measures the content of salts of the alkaline earth metals calcium, magnesium, strontium and barium in freshwater. For the determination the titrant is added dropwise to the sample until the added indicator changes its color.
This MQuant® Total Hardness test (formally MColortest®) is suitable for the titrimetric determination using a convenient dropping bottle.
Method
Calcium and magnesium ions react with an indicator to form a red complex compound. The indicator is released from this compound by titration with a solution of ethylenedinitrilotetraacetic acid disodium salt dihydrate (Titriplex® III). At the titration end-point the color changes to green. The total hardness is determined from the consumption of titration solution.
