Italiano: Per determinare il contenuto di manganese in un campione di pirolusite, ne si inseriscono circa esattamente 0.436 g in un palloncino B assieme a dell'acido cloridrico. Per riscaldamento su fornelletto L si producono vapori di cloro, raccolti da un tubo C e gorgogliati in una provetta E con soluzione nota di ioduro di potassio. Dopo pochi minuti l'emissione di cloro cessa, e la soluzione viene titolata per iodometria, con tiosolfato sodico e salda d'amido.
English: To determine the manganese content in a pyrolusite sample, exactly around 0.436 g are placed in a small round bottom flask B connected by a pipe C to a test tube E filled with a known solution of potassium iodide. After a few minutes the flow of chlorine stops, and the solution is titrated with sodium thiosulphate and starch. |
