Therefore another improvement in the experiment is to add a sample bottle into the apparatus, this would keep the HCl away from the CaCO3.
The factors that would affect the rate of reaction would be: The chips are then added and the bung is quickly placed over the flask to create an airtight seal. Then you add a certain amount of HCl, about 50cm3 and put both of these onto a weighing scale.
This is because at the molecular level, there are more molecules at the surface of the chips for the molecules of acid to react with when the chips are broken into smaller pieces. Therefore I deduce that if I use 5g of mm chips the surface area will still remain constant to a certain extent.
So to get around this problem you could repeat the experiment 3 times and then produce an average. This suggests that we had lost gas and then gained more gas in the span of 20 seconds. Calcium carbonate, also known as marble, is a metamorphic rock. The first experiment is the one which threw the average off.
The speed at which the reactants will create the products is called the rate of reaction. The smaller the chips the more surface area so I predict that the smaller marble chips will react faster than the larger chips.
Between them are strong bonds that hold them together in a fixed place. The above calculations clearly prove that if you double the concentration you will double the rate of the CO2 loss.
During the execution of my practical I was very accurate with my measurements and tidy with my work space. If I was to test this experiment again, the only thing that I would change would be to use higher concentrations of Hydrochloric Acid.
This is where the energy needed in order to break the bonds is reduced. Evaluation I believe that my results are very good, apart from one anomalous point all the others fit comfortably on a line of best fit. When hydrochloric acid reacts with calcium carbonate the products are calcium chloride, water, and carbon dioxide.
The particles in a gas are much further apart than in a solid or liquid, and have very weak bonds that allow them to move quite freely.Rate of Reaction Between Calcium Carbonate and Hydrochloric Acid Essay - Rate of Reaction Between Calcium Carbonate and Hydrochloric Acid Planning ===== The aim is too investigate what factors affect the rate of reaction between calcium carbonate and hydrochloric acid.
The reaction between marble chips - Sample Essay The mass will simply be kept constant by having 5g of CaCO3 each time. But the surface area is difficult to keep constant considering that the chips are roughly the same size but irregular shapes and so the surface area may differ.

Methods of Measurement. I will add calcium carbonate (marble chips) to hydrochloric acid. When calcium carbonate is added to hydrochloric acid a reaction takes place.
The solution fizzes and gives off the gas carbon dioxide/5(1). The formula for this reaction is: Hydrochloric acid + Calcium carbonate Calcium chloride + Water + Carbon dioxide HCl(aq) + CaCO3(s) CaCl2(aq) + H2O(l) CO2 As you can see above, in the reaction, the reactants are hydrochloric acid and calcium carbonate, and the products are calcium chloride, a salt, water and carbon dioxide.Download
