General description
This refill pack contains the reagent H-1 for the MQuant® test kit 1.08039 for the colorimetric evaluation of total hardness. When the reagents of the MQuant® test are used up, the kit can be replenished by ordering the appropriate refill pack. Refill packs are available for a range of MQuant® test kits, making it a particularly economical and ecological system.
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.
