Oxidation states of the metal in the minerals cassiterite and stannite, respectively are:
II, IV in cassiterite and II in stannite
II, IV in cassiterite and IV in stannite
IV in cassiterite and II, IV in stannite
II in cassiterite and II, IV in stannite
Cassiterite is a mineral composed of tin dioxide . In this mineral, the oxidation state of tin
is
. Each tin atom in cassiterite has four oxygen atoms bonded to it, resulting in the oxidation state of
for tin.
Stannite is a mineral composed of a complex sulfide of tin, copper, and iron. The oxidation state of tin in stannite can vary. It can exist in both the and
oxidation states. Therefore, the oxidation states of metals in stannite are II and IV.
