Properties: Silver-white, lustrous, soft, very malleable and ductile metal; only slightly tenacious; easily powdered. When being bent, emits the crackling "tin cry". Brittle at 200°. At -40° crumbles to gray amorphous powder ("gray tin"), slowly changing back above 20° to white tin. Available in the form of bars, foil, powder, shot, etc. Stable in air, but when in powder form it oxidizes, esp in presence of moisture. d 7.31. mp 231.9°. bp 2507° (2780 K). Specific heat (25°) 0.053 cal/g/°C. Brinell hardness 2.9. Insol in water. Reacts slowly with cold dil HCl or dil HNO3, hot dil H2SO4; readily with concd HCl, aqua regia; very slowly attacked by acetic acid; slowly attacked by cold, more readily by hot caustic alkali; concd HNO3 converts it into insol metastannic acid.
Melting point: mp 231.9°
Boiling point: bp 2507° (2780 K)
Density: d 7.31
CAUTION: Potential symptoms of overexposure to metallic tin are irritation of eyes, skin, respiratory system. Potential symptoms of overexposure to organic tin compounds are irritation of eyes, skin, respiratory system; headache, vertigo; psychoneurologic disturbances; sore throat, cough; abdominal pain, vomiting; urine retention; paresis, focal anesthesia; skin burns; pruritis.
