Investigating the Rate of Reaction Between Marble Chips And HCL Safety- must always wear safety glasses and we should be very careful not to drop any acid. Fair test- we must make sure that we use the same size, amount and roughly the same mass of chips, this is because we want to keep the chips roughly the same all the way through the experiment so that it will be a fair test and the …

…thought would happen did. At this point we are able to answer our main hypothesis which was how does changing the concentration of acid affect the rate of reaction between hydrochloric acid and calcium carbonate. The answer to this would be that changing the concentration of the acid will either make it go slower or quicker and more or less gas would be produced depending on whether the concentrations were more or less Bibliography na
