Stannic acid
From Wikipedia, the free encyclopedia
Stannic acid refers to hydrated tin dioxide, SnO2. The character of this is debatable. Also called stannic hydroxide, it can be given formula Sn(OH)4.
In line with the almost contradictory names, stannic acid is amphoteric.
Stannic acid dissolves in base to form stannate ion, Sn(OH)62-. This can then form stannate compounds.
In strongly acid conditions, it forms tin(IV) ion, Sn4+.
Stannic acid is a poor oxidizer. Combined with a good reducing agent, it can form stannous hydroxide, Sn(OH)2, but is as likely to form tin metal.
