For amateur pyros, each of these methods may be used as we need not be concerned with the economy of the process as much as commercial operations do. Therefore, the amount of electricity that went through a cell is calculated by multiplying the current going through the cell (in amperes) by the time it has been flowing (in hours). Due to the low solubility of potassium perchlorate a large volume of water may be needed then. sodium chloride Adding a solution of barium chloride to the electrolyte will precipitate any chromate or dichromate as the corresponding barium compounds. pKa = 4.40. No smoking. Barium perchlorate is also used for the determination of small concentrations (down to 10 ppm, with an accuracy of +/- 1 ppm) of sulfate. If any other method is used to destroy residual chlorate the pH must always be adjusted afterwards to slightly above 7. Sodium perchlorate can be made directly from sodium chloride by electrolysis in which case no special electrolyte for the chlorate to perchlorate step has to be prepared.
