Lead dioxide anodes are not easily bought and must be made. [3] Another method of preparation involves the digestion of a saturated solution of ammonium perchlorate with hydrated barium hydroxide in 5-10% excess of the theoretical amount. In the past, thermal decomposition of chlorate has been used but since this process is very inefficient it has been abandoned long ago. Barium hydroxide is a group IIA metal hydroxide and it dissolves very well in water . Ammonium perchlorate suffers slightly worse losses when recrystallised, but still acceptable. The influence of cell temperature is two-fold: anode erosion increases with increasing cell temperature and the cell voltage is reduced at higher temperatures. Iron(II)sulfate is another option, and the chemical can be bought in some gardening supply shops as it is used to supply plants with iron.

Some are naturally present i A: According to the second law of thermodynamics, the spontaneous nature of the reaction is determined A: Potassium Fluoride(KF) is a salt. Since chlorates and perchlorates behave very differently in pyrotechnic compositions chlorate contamination can be very dangerous. The need for dehydrating compounds has increased with the use of chemical reactions employing gases under pressure, as the water must be removed from the air prior to the reaction taking place.[8]. 4 Does dehydration of barium perchlorate cause hydrolysis? If this is not done, traces of acid may be included in the final product making it very dangerous to use in pyrotechnic compositions.
