General description
This MQuant® Total Hardness test (formally MColortest®) is suitable for the titrimetric determination using a graduated syringe. It can be used in:•Groundwater, surface water, and seawater•Waters from aquaculture•Drinking water and mineral water•Swimming-pool water•Boiler waterMethodCalcium 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.
