It consists of tin dioxide, or stannic oxide (SnO2), and crystallizes in the tetragonal system.
By adding hydrate of potassium or an alkaline carbonate to a solution of stannic chloride.
This will bring his result, if calculated as stannic oxide, to 80.9 lbs.
After standing about twelve hours in a covered beaker the precipitate was filtered off and the tin weighed as stannic oxide.
stannic oxide when ignited with chlorides is more or less completely converted into stannic chloride, which volatilises.
If tin be present there will be an insoluble residue left of stannic oxide.
Double salts of cerous chloride with stannic chloride, mercuric chloride, and platinic chloride are also known.
Protoxide of tin takes fire in the flame of oxidation, and burns with flame and some white vapor into tin acid, or stannic acid.
Tin in solution as stannic or stannous chloride is precipitated as metal by means of zinc.
Stannous chloride is usually sufficiently contaminated with stannic salt.
"containing tin," 1790, from Modern Latin stannum, from Late Latin stannum "tin" (earlier "alloy of silver and lead"), a scribal alteration of Latin stagnum, probably from a Celtic source (cf. Irish stan "tin," Cornish and Breton sten, Welsh ystaen). The Latin word is the source of Italian stagno, French étain, Spanish estaño "tin."
