stannite (ion)

The stannite ion is {{chem2|[Sn(OH)3]−}}. It can be formed by adding strong base to stannous hydroxide.{{Cite journal |last1=Dickinson |first1=T. |last2=Lotfi |first2=S. |date=October 1978 |title=The nature and standard potential of the stannite ion in sodium hydroxide solutions |url=https://linkinghub.elsevier.com/retrieve/pii/0013468678850051 |journal=Electrochimica Acta |language=en |volume=23 |issue=10 |pages=995–999 |doi=10.1016/0013-4686(78)85005-1|url-access=subscription }} The stannite ion is a strong reducing agent;{{Cite book |last1=Bailey |first1=Edgar Henry Summerfield |url=https://books.google.com/books?id=laRPAAAAYAAJ |title=A Laboratory Guide to the Study of Qualitative Analysis |last2=Cady |first2=Hamilton Perkins |date=1901 |publisher=P.
