Precautions hydrogen sulphide

Note Hydrogen sulphide is a highly poisonous gas, and all operations with the gas must be conducted in the fume chamber. Every precaution must be observed to prevent the escape of hydrogen sulphide into the air of the laboratory. [Pg.196]

Cupric sulphide, CuS.—By adopting special experimental precautions, it is possible to prepare cupric sulphide free from cuprous sulphide and sulphur by precipitating a solution of cupric sulphate or chloride with hydrogen sulphide,8 although if no precautions are taken the precipitate is likely to be contaminated with these substances.9 At 180° C. concentrated sulphuric acid converts copper into a mixture of cupric sulphide and sulphur, from which the sulphur can be removed by heating at 160° C. in a rapid current of hydrogen.10... [Pg.278]
