Tin(IV) chloride
Tin(IV) chloride, also known as stannic chloride is a chemical compound with the formula SnCl4.
At room temperature it is a colourless liquid, which fumes on contact with air, giving a stinging odour.
Its molecular weight is 260.5, its boiling point 114°C, and its
freezing point -32°C. It is also known as tin tetrachloride. Anhydrous tin(IV) chloride is a strong Lewis acid which reacts violently with water. It is extremely corrosive to skin. On contact with air it releases severely irritating hydrogen chloride fumes. It forms a white pentahydrate. Stannic chloride was used as a chemical weapon in World War I.
