Reagecon's EDTA 0,05 M is a fully factorised, high purity, stable product, developed and tested for titrations. This is an analytical volumetric solution, also called titrant, standard titrant or standard solution. It is a reagent of known concentration, that is dispensed from a burette or other dispensing apparatus to a sample (analyte), until a reaction between the two liquids is judged to be complete. The product may be used for manual titrations, or more commonly automatic titrations also called potentiometric titration, to determine the end points by detection of any of several properties as detailed in several ChP monographs.
