Perchloric acid is best prepared by distilling potassium perchlorate with concentrated sulphuric acid.
The best way to obtain pure oxygen directly is to take potassium perchlorate (KClO{4}), which can be well purified and then evolves pure oxygen on heating.
Thus there is now no doubt that when potassium chlorate is heated, the perchlorate is formed, and that this salt, in decomposing with evolution of oxygen, again gives the former salt.
On decomposing a solution of potassium chlorate by the action of an electric current, potassium perchlorate is obtained at the positive electrode (where the oxygen is evolved).
It is indispensable, however, for the success of the experiment that the perchlorate of potassium be absolutely free from chlorate.
The liquid immediately surrounding the perchlorate will at once assume a deep brown colour, which will soon spread and extend over the greater part of the acid.
Platinum chloride does not give a precipitate with sodium chloride; neither does picric acid, perchlorate of ammonium, nor tartaric acid.
A potassiumperchlorate explosive made by the Carbonite Syndicate at Schlebusch in Germany.
Part of theperchlorate may be replaced by nitrate.
A German potassium perchlorate blasting explosive made by Wolff et Cie.
It was apparently a chlorate orperchlorate explosive.
A German perchlorate blasting explosive made by the Koeln-Rottweil Pulverfabriken.
Three parts of sulphuric acid and one of chlorate of potassa, when heated, will give a saline mass, consisting of bisulphate of potassa, and perchlorate of potassa.
The perchlorate detonates feebly when triturated with sulphur.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "perchlorate" in a variety of sentences. We hope that you will now be able to make sentences using this word.
