Abstract

The spectrophotometry and radioactive exchange of Sn^II and Sn^IV in hydrochloric acid have been investigated. It is found that mixtures of Sn^II and Sn^IV in hydrochloric acid exhibit anomalous absorption of ultra-violet light and that with the extent of this anomalous absorption is proportional to the product of the Sn^II and Sn^IV concentrations, implying absorption by a dimeric complex of Sn^II and Sn^IV.

It is found that Sn^II and Sn^IV exchange radioactivity moderately slowly (half-exchange time about 7 min.) in 9N hydrochloric acid. The extent of exchange upon immediate separation after mixing is about 17%, which is either a function of the separation method or an indication that only certain chloride complexes of tin exchange.

It is found that Cu^I and Cu^II exhibit interaction absorption in 6N HCl
