Apparatus according to Schlössing for the determination of ammoniacal nitrogen in drinking water

Summary[edit]

Description
Italiano: Un pallone contenente 0.5-1 L di acqua da analizzare viene messa a bollire con ossido di magnesio MgO. I vapori sono condensati in un becher con dell'acido in quantità nota (solitamente acido ossalico) e per titolazione dell'acido neutralizzato si ricava la quantità di azoto ammoniacale presente nell'acqua potabile analizzata.
English: A round-bottom flask with 0.5-1 L of drinking water to be analyzed is boiled with magnesium oxide MgO. The ammoniacal vapours are collected and condensed in a beaker with a known amount of acid (usually oxalic acid). By titration of the excess acid, the amount of ammoniacal nitrogen can be calculated.
