How much water is displaced during the reaction between limestone and hydrochloric acid?

Extracts from this document...


How much water is displaced during the reaction between limestone and hydrochloric acid? The reaction- Calcium carbonate + hydrochloric acid = calcium chloride + water + carbon dioxide CaCO3 + HCI = CaC12 + H2O + CO2 Input Variables In the experiment we could change the following: * Temperature * Concentration of acid * Amount of calcium carbonate * Amount of acid * Add catalyst Prediction I predict that in this experiment the higher the concentration of acid the faster the reaction will occur. This would mean that more hydrogen is produced making the water displace faster in the measuring cylinder. The smaller the stones are, the even quicker the reaction will happen; this is because the acid has a smaller surface area to act upon. Explanation As the higher the concentration of acid is added the faster the reaction. The medium chips react faster as there is a smaller surface area to act upon then the large chips. This turn increases the amount of particle collision and therefore the reaction takes place quicker. Background Info Marble is made from limestone that has been metamorphosed and re crystallised due to the action of heat. ...read more.


To get the best results I need to use the equipment in the best possible way. Some ways of doing this would be to twist the gas syringe back and forth so as to not get the syringe stuck, which could affect our results. Another thing would be to sieve the chips so to get the best marbles we can. An important point is that I must get the right amount of acid and the best size and amount of marbles. This is where my trial experiments, that I did before I started, came in handy because it allowed me to know what amount and size of chips to use. After doing my trial experiments I worked out that 100g of medium sized chip would be best to use. But I must remember that if I use 100g's of chips then I must use 100g's of chips roughly the same size all the way through on all the different concentrations.

The only possibility was if the temperature of the acid had changed from when we did the first reading to the finish i.e. from when we did the first experiment, the acid hopefully would have been the same temperature. From looking at my results and graph I am able to conclude that the more concentrated the acid the quicker the reaction happened and the more gas was produced. As we look at the graph we can clearly see that in all five results at the beginning the reaction happened more quickly than at the end where we can see that it started to tail off. Before I did the experiments I made some predictions they were that the more concentrated the acid was the quicker the reaction [1] would happen and more hydrogen would be produced. This was completely correct because what I 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. ...read more.
