Usage examples of "acids".
But any method for thus combining the bases and acids must be arbitrary and inaccurate.
It is almost always used in those cases where mineral acids are objectionable.
Sulphur, phosphorus, and arsenic are converted into sulphuric, phosphoric, and arsenic acids respectively, when boiled with the strong acid.
It is used for the purpose of separating phosphoric oxide from bases and from other acids, and also as a test for phosphates and arsenates.
These were carefully neutralised with the respective acids, rendered alkaline with 30 c.
The wet precipitate is very bulky, of a dark-brown colour and readily soluble in dilute acids, but insoluble in ammonia and dilute alkalies.
Arsenic and phosphoric acids interfere unless an excess of free hydrochloric or other acid is present.
The more strictly chemical methods are rendered troublesome by the oxide being insoluble in acids, resembling in this respect the gangue with which it is associated.
The reduced metal is only slowly dissolved by hydrochloric acid, and although it is readily soluble in aqua regia, the solution cannot be evaporated or freed from the excess of acids, by boiling, without loss of tin, because of the volatility of stannic chloride.
After ignition, it is insoluble in acids, except sulphuric, but is rendered soluble by fusion with alkalies.
They are converted into this form, if none of the stronger acids are present, by simply evaporating with an excess of hydrochloric acid.
For the determination, it is not necessary to obtain the solution of the chloride free from other acids or metals.

If the dish becomes stained during evaporation, take up with a few drops of hydrochloric and sulphurous acids, evaporate, and then treat with carbonate of soda.
Slags are for the most part decomposed by boiling with aqua regia, but it will be found more convenient and accurate to first extract with acids and then to treat the residue as an insoluble silicate.
