Total Hardness Test Refill pack Reagent H-2 (titration solution)

Descrição detalhada : This refill pack contains the reagent H-2 for the MQuant(R) test kit 1.08039 for the colorimetric evaluation of total hardness. When the reagents of the MQuant(R) test are used up, the kit can be replenished by ordering the appropriate refill pack. Refill packs are available for a range of MQuant(R) test kits, making it a particularly economical and ecological system.MethodCalcium 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(R) III). At the titration end-point the color changes to green. The total hardness is determined from the consumption of titration solution.
