How does tin react with steam?

Answer 1

Tin(II) oxide (stannous oxide) is a compound with the formula SnO. It is composed of tin and oxygen where tin has the oxidation state of +2. There are two forms, a stable blue-black form and a metastable red form.

Blue-black SnO can be prepared by heating the tin(II) oxide hydrate, SnO.xH2O (x<1) precipitated when a tin(II) salt is reacted with an alkali hydroxide such as NaOH.[3] Metastable, red SnO can be prepared by gentle heating of the precipitate produced by the action of aqueous ammonia on a tin(II) salt.[3] SnO may be prepared as a pure substance in the laboratory, by controlled heating of tin(II) oxalate (stannous oxalate) in the absence of air.[4]SnC2O4 → SnO + CO2 + CO

Tin(II) oxide burns in air with a dim green flame to form SnO2.[3]2 SnO + O2 → 2 SnO2

When heated in an inert atmosphere initially disproportionation occurs giving Sn metal and Sn3O4 which further reacts to give SnO2 and Sn metal.[3]4SnO → Sn3O4 + SnSn3O4 → 2SnO2 + Sn

SnO is amphoteric, dissolving in strong acid to give tin(II) salts and in strong base to give stannites containing Sn(OH)3−. It also dissolves in strong acid solutions to give the ionic complexes Sn(OH2)32+ and Sn(OH)(OH2)2+, and in less acid solutions to give Sn3(OH)42+. Note that anhydrous stannites, e.g. K2Sn2O3, K2SnO2 are also known. SnO is a reducing agent and this appears to its role in the manufacture of so-called "copper ruby glass".

Answer 2

Tin does not react with steam, as it is generally unreactive with water at normal temperatures. However, in the presence of steam at high temperatures, tin can react to form tin dioxide, with the release of hydrogen gas.

Answer 3

The electronegativity of tin is 1,96; tin react (or form alloys) with the majority of other chemical elements.
