Abstract:

The current study was carried out to measure the heat resulting from the spontaneous dissociation of some inorganic salts by using sodium chlorate and ammonium perchlorate salts (3gm), iron filings (22gm) with grain size (350 µ), sawdust (7gm) with a size of (200 µ), activated carbon (7gm), and distilled water (8ml), The speed of the reaction was measured and found it was second degree (n=2). Measurement of the heat of the reaction emitted was also studied in several ways, including the direct method from the Vant-Hoff equation and the calorimetric method, in addition to comparing it with the theoretical value of standard heat of formation which showed the dependence of the reaction temperature on the two salts. Moreover, classical methods were used to determine the amount of chlorate and perchlorate radicals by depositional gravimetric analysis and volatilization methods.
