Experiment 12 Aim: To determine the activation energy of the reaction between Bromide ion and Bromate(V) ion in acid solution Procedure 1. 10.0cm3 of 0.01M phenol solution, 10.0 cm3 solution A (0.083M with respect to KBr and 0.017 M with respect to KBrO3) and 10 drops of methyl red indicator were placed into a boiling tube. 2. 5.0 cm3 of 0.5M sulphuric(VI) acid was placed into a second boiling tube. 3. Both boiling tubes were placed into a beaker of water which is maintained at about 30ºC. The contents of the tubes were allowed to reach the temperature of the water bath. 4. The sulphuric(VI) acid was poured into the first boiling tube, and at the same time the stop watch was started. The boiling tube was swirled gently. 5. The first boiling tube was kept in the water bath throughout the experiment. The time (t) taken was recorded, to the nearest second, for the complete disappearance of...
