When hydrosulphuric acid (H{2}S) is passed into a solution of this chloride the hydrogen and antimony exchange places; write the equation for the reaction.
It can also be prepared by passing hydrosulphuric acid into water in which iodine is suspended.
Account for the fact that paints made of zinc oxide are not colored by hydrosulphuric acid.
Consequently, when hydrosulphuric acid is passed into a solution of a salt, it often happens that a sulphide is precipitated.
Owing to the ease with which hydrosulphuric acid decomposes and the strong affinity of both sulphur and hydrogen for oxygen, the substance is a strong reducing agent, taking oxygen away from many substances which contain it.
By passinghydrosulphuric acid into a solution of a mercuric salt it is precipitated as a black powder, insoluble in water and acids.
This is due to the fact that chromic sulphide, like aluminium sulphide, hydrolyzes in the presence of water, forming chromic hydroxide and hydrosulphuric acid.
It can be obtained in the form of a black solid by passing hydrosulphuric acid through a solution of silver nitrate.
The elements composing hydrosulphuric acid have each a strong affinity for oxygen, and are not held together very firmly.
Thus, when chlorine is passed into a solution containing hydrosulphuric acid, sulphur is precipitated and Hydrochloric acid formed.
Their solutions are known by the following reactions:--They are not precipitated by hydrosulphuric acid when acid, and but incompletely when neutral.
Precipitate by hydrosulphuric acid, and reduce as III.
Hydrosulphuric acid in acid solutions reduces ferric to ferrous salts, giving a white or yellow precipitate of sulphur only.
It remains limpid on the addition of lime water, chloride of barium, nitrate of silver, oxalate of ammonium, or hydrosulphuric acid.
The colour is not changed by the addition of hydrosulphuric acid.
In Gmelin's Handbook of Chemistry it is remarked that "Hydrogen gas passed over ignited ultramarine, colours it light red, from formation of liver of sulphur, hydrosulphuric acid gas and water being evolved at the same time.
Sufficient hydrosulphuric acid gas was evolved to blacken paper moistened with acetate of lead, a fact which proved that the blue had lost some of its sulphur.
This is also most marked if we treat the two withhydrosulphuric acid solution (sulphuretted hydrogen[5]).
If the fixing bath be acid, the excess of acid combines with the sulphur, and forms hydrosulphuric acid, which will also cause the defect.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "hydrosulphuric" in a variety of sentences. We hope that you will now be able to make sentences using this word.
