general description |
white tin is an almost silver-white, ductile, malleable, lustrous solid. mp 232°c; bp: 2507°c. density: 7.3 g cm-3. pure white tin becomes non-metallic powdery gray tin if held for a sustained period at temperatures less than 13°c. |
|
reactivity profile |
tin is a reducing agent. stable in massive form in air, but oxidizes (corrodes) in air as a powder, especially in the presence of water. dissolve slowly in dilute strong acids in the cold. dissolves in hot aqueous koh and other strongly basic solutions. incompatible with acids and base. incompatible with chlorine and turpentine. |
