Tin: its oxidation states and reactions with it

Tin is a light met­al lo­­ed in the 14th group of the pe­ri­od­ic ta­ble, with the atom­ic num­ber of 50 This el­e­ment has been known to hu­man­i­ty since an­cient times and was con­sid­ered to be one of the rarest and most valu­able met­als, so items made from tin could only be af­ford­ed by the rich­est in­hab­i­tants of the Ro­man Em­pire and An­cient Greece...

Tin(IV) oxide

Tin(IV) oxide, also known as stannic oxide, is the inorganic compound with the formula SnO 2The mineral form of SnO 2 is called cassiterite, and this is the main ore of tin With many other names, this oxide of tin is an important material in tin chemistry It is a colourless, diamagnetic, amphoteric sol...

extraction of metals

However, if you are starting with a sulphide ore, for example, that's not a lot of help! It is much more helpful to use the definition of reduction in terms of addition of electrons To a reasonable approximation, you can think of these ores as containing positive metal ions To convert them to the metal, you need to add electrons - reduction...
