Reagecon's Ammonia Concentrated Volumetric Solution, Ampoule to make 1L of 0.1M (0.1N) Ammonia is a fully factorised, high purity, stable product, developed and tested for titrations. This Analytical Volumetric Solution, is 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, to determine the end points by detection of any of several properties. When the product is accurately diluted to one litre in a volumetric flask, it can then be used as an Analytical Volumetric Solution, to a specification of ± 0.2%.
