Webb15 aug. 2024 · Density 7.30 g/cm 3 Characteristics: Metallic tin is soft and malleable. It slowly dissolves in dilute nonoxidizing acids or more readily in hot concentrated HCl. It reacts with HNO 3 to form metastannic acid, H 2SnO 3, a white substance insoluble in alkalies or acids. WebbTin Oxidation States . Tin exists in two oxidation states: +2 and +4. Elemental tin readily oxidizes to the 2+ ion in acidic solution; this compound can also convert to the +4 ion when mixed with mild oxidizing agents. Isolation of Tin. Pure tin is easy to make, by simply placing a more reactive metal like zinc into a solution of tin (II) chloride.
