The goods are left thus exposed to the sulphur dioxide overnight, when they are taken out and washed in water.
Gustav brought with him, too, the refilled drums of sulphur dioxide.
Sulphuretted hydrogen and sulphur dioxide reduce them in acid solution to the condition of chromium salts.
In this chapter we shall consider the systems formed by the two components iodine and chlorine, and sulphur dioxide and water.
It burns when heated in air, forming the pentoxide and sulphur dioxide.
The case of sulphur dioxide and water is also of interest from the fact that two liquid phases can be formed.
Pictet liquefied carbonic acid and sulphur dioxide by pressure.
Before the melting point of the monohydrate is reached, two liquid phases are formed, as in the case of sulphur dioxide and water.
Boiling concentrated sulphuric acid converts lead into sulphate, with evolution of sulphur dioxide.
sulphur dioxide gas can now be obtained compressed in cylinders, which are more convenient to handle than burning sulphur.
