To quickly assess the difficulty of the text, read a short excerpt:
CHLORIDE OF TELLURIUM (TeCl) obtained by strongly heating the metal in a feeble current of chlorine, is a black solid ; its vapor is violet-colored. Water decomposes the chloride into bichloride and metal. The bichloride (TeCl a ) is prepared by gently heating tellurium in an excess of chlorine ; it is a white, crystalline, volatile solid, soluble in water. A bisulphide and a tersulphide of tellurium are known ; the latter is very un- stable. These sulphides are sulphur-acids. The tellurides of... the metals are very similar to the sulphides and selenides. The alkaline tellurides have a reddish-brown color, and yield red solutions. When a telluride is boiled with nitric acid, tellurous acid is formed, the other metal being converted into a nitrate. REACTIONS OP TELLURIUM (Tellurous acid). Alkalies and their carbo- nates ; white precipitate, soluble in excess. Bydrosulphuric acid, in acid solutions, brown precipitate, soluble in the alka- line sulphides. Reducing agents, e. G. Sulphurous acid, chloride of tin, zinc, &c.
