Reduktion nicht zerstört werden.
Beispiel 4 : Als Beispiel für die Anwendung der Reduktion von anorganischen Stoffen sei die Reduktion von Eisenoxydsalzen zu Oxydulsalzen angeführt. Kocht man Lösungen von Eisenchlorid mit Bisulfit und Ameisensäure, so findet unter Entfärbung der Flüssigkeit Reduktion statt, was die beiden Stoffe einzeln nicht vermögen. Dasselbe ist der Fall bei dem technischen, holzessigsauren Eisen, einer fast schwarzen Lösung von teilweise oxydiertem essigsaurem Eisenoxydul. Diese Eigenschaft hat eine praktische Bedeutung in der Druckerei, z. B. beim Druck von Eisenchamois, von Dampfalizarinviolett usw. Bei diesen Verfahren müssen die Eisensalze als Oxydulsalze verwendet werden, da die Oxydsalze sich nicht mit der Faser verbinden.
Da nun die Oxydulsalze sich von selbst an der Luft sehr leicht oxydieren und dadurch die Druckfarben unbrauchbar werden bzw. schlecht fixierte Drucke geben, fügt mass als Reduktionsmittel arsonik- saures Natrium oder Kupferarsenit hinzu. Diese giftigen und auch@teueren Salze können vorteilhaft durch Salze der schwefeligen Säure und Ameisensäure ersetzt werden.

EMI2.1
Reduction cannot be destroyed.
Example 4: As an example of the application of the reduction of inorganic substances, the reduction of iron oxide salts to oxide salts is given. If solutions of ferric chloride are boiled with bisulfite and formic acid, reduction takes place with discoloration of the liquid, which the two substances cannot do individually. The same is the case with technical iron, wood acetic acid, an almost black solution of partially oxidized acetic iron oxide. This property is of practical importance in printing, e.g. B. when printing iron chamois, steam alizarin violet, etc. In these processes the iron salts must be used as oxide salts, since the oxide salts do not combine with the fiber.
Since the oxide salts oxidize themselves very easily in the air, making the printing inks unusable or giving poorly fixed prints, massively adds arsonic acid sodium or copper arsenite as a reducing agent. These toxic and expensive salts can advantageously be replaced by salts of sulphurous acid and formic acid.
