An Experiment to investigate whether the concentration of HCl affects the rate of reaction with CaCO3 PLANNING Aim: My aim for this experiment is to find out if the concentration affects the rate of reaction between CaCO3 & HCl. Prediction: I predict that the high molarity concentration solution will have a much faster rate of reaction than the weaker solution. I have predicted this from my knowledge of a previous experiment and scientific knowledge. Recently I did a similar experiment involving a sodium thiosolphate cross instead of the calcium carbonate, from this I found that the higher concentration solutions, faster the reaction, therefore I believe the same results may occur. The speed of the reaction was proportional to the concentration of the reactant, which I predict, will also happen in our experiment. I think that this happened because the more HCl in the solution the greater the concentration and there will be...
