Rate of reaction between Hydrochloric Acid and Calcium Carbonate Essay

Rate of reaction in the midst of Hydrochloric superman and Calcium centuryateCalcium coulombate reacts with hydrochloric acidulous to form carbon dioxidegas. One way of following the regularise of reaction at which it reacts isto amount the volume of carbon dioxide produced at certain timeintervals during the reaction.CaCO + 2HCl CaCl + H O + CO===========================Calcium Carbonate + Hydrochloric Acid Calcium Chloride + Water+ Carbon DioxideEquipment---------Delivery tubeConical flaskHydrochloric acidCalcium carbonate chipsBuretteBeaker electric scalesMeasuring cylinderTubWaterElectric timerGogglesRetort standThe different factors that can require-to doe with my essay are thetemperature, the concentration of my reactants and the surface area,also adding a catalyst. We have decided to test differentconcentrations of hydrochloric acid for our investigate because it volition charge us sufficient results to make our evidence reliable.RATE OF REACTION surrounded byHYDRO CHLORIC ACID AND CALCIUM CARBONATELOW niggardnessHIGH CONCENTRATIONI think that during our experiment, the higher the subity of acidthe quicker the rate of reaction will be, I think this because of thecollision theory. If the solution is make more concentrated, therewill be more particles in the solution. This makes collisions betweenimportant molecules more likely and will collide more often. At thebeginning of the reaction, there are lots of reactants particles (andno products). This means a lot of productive collisions betweenreactants. As time goes on these reactants will become less(prenominal) and less(because reactants have been turned into products), therefore lesscollisions, so the rate of reaction will slow down. If the molarity ofthe acid concentratio... ...act same size wecould use 2 chips in one experiment and get 1g then we could use 4chips in another experiment and still get 1g. This meant that thesurface area for the hydrochloric acid changed in separately experi ment forit to react and collide with. I could have stopped this by sieving soI would get chips that are of the same or nigh enough the samesurface area.Over every last(predicate) my results are fairly reliable, tho could be subjective tochange if better methods were available. If I was to do my experimentagain I would make sure I would do it all on the same day and maybechange the limits of the products so that the results we got could bemore accurate and we would have less anomalous results like the 2.5molar experiment. However, if I did this experiment again I wouldexpect the same results and patterns that I have got apart from the2.5 molar and 3 molar experiments.
