[edit]DescriptionAubin's distillation apparatus for the determination of ammonia (Alessandri 1895.28).png |
Italiano: Un pallone A contenente il solido da analizzare digerito in idrossido di sodio viene collegato ad una serpentina a spire larghe B, ed un condensatore verticale C. L'acqua di raffreddamento R entra nel condensatore tramite H ed E e lo abbandona tramite F e G. L'acqua ammoniacale distillata viene raccolta in un becher D contenente un acido in quantità nota. Titolando l'acido rimanente è possibile quantificare l'ammoniaca prodotta.
English: A round-bottom flask with the solid to be analyzed A is digested with sodium hydroxide and connected to a wide glass spiral B and a vertical condenser C. The system is cooled through the network R, H, E, F and G. By collecting the ammoniacal distillate in a beaker D with a known excess of acid, it is possible to determine the nitrogen content as ammoniacal nitrogen. |
