... entration had reached 36.5cm3 of gas collected). Whereas the 0.4M of acid started and ended with the least gas collected (by thirty seconds only 8.5cm3 of gas had been collected). However, according to my prediction these results should have shown that the higher the concentration of acid should give a steeper graph with the reaction finishing much quicker. Despite, my results I still think that my prediction was a correct one. I think that it is not the prediction but the results that are incorrect.
