That it is more poisonous than the hydrogen sulphide is well known.
The main element in the change is the production of hydrogen sulphide.
hydrogen sulphide converts the mixture into a similar suspension of the black sulphide.
If hydrogen sulphide is passed through a solution of methylene blue the dye is very quickly reduced and becomes colorless.
hydrogen sulphide was passed into the ether solution mixed with water to remove the lead.
Concentrated acids destroy the hair with the liberation or formation of ammonia, hydrogen sulphide, and various amino acids.
The alcoholic solution of this third lot gave no precipitate with hydrogen sulphide.
The solution thus obtained was properly diluted and saturated with hydrogen sulphide.
hydrogen sulphide, Dihydric sulphide, Hydric sulphide; Hydrosulphuric acid.
The decomposition continues until the whole of the hydrogen sulphide is converted into gaseous fluorides of hydrogen and sulphur.
