Abstract

The dissolution of zinc in 0.48–1.49M HNO3 was studied at 15–25°C, by following simultaneously the concentration changes of the reactants (Zn and HNO3), intermediate (HNO2) and product (Zn2+) with time. Explicit mechanisms were suggested for the dissolution of zinc in nitric acid. The kinetics of the dissolution process show that it is of the first-order with respect to [Zn] and [HNO2]. The data obtained show that the dissolution process is diffusion-controlled. The mechanism of zinc dissolution is compared with the mechanism of copper dissolution.

Die Kinetik der Auflösung von Zink in Salpetersäure

Zusammenfassung

Die Auflösung von Zink in 0.48–1.49M HNO3 wurde bei 15–25°C mittels gleichzeitiger Verfolgung der Konzentrationsänderungen der Reaktanden (Zn und HNO3), des intermediären HNO2 und des Produkts Zn2+ untersucht. Es wird ein Mechanismus vorgeschlagen. Die Kinetik der Auflösung ist erster Ordnung bezüglich [Zn] und [HNO2]. Die Daten zeigen, daß der Auflösungsvorgang diffusionskontrolliert ist. Der Mechanismus der Auflösung von Zink wird mit dem der Kupferauflösung verglichen.
