Investigation looking At the Speed of Reactions :: GCSE Chemistry Coursework Investigation

Investigation sounding At the Speed of ReactionsIntroductionThe aim of this experiment is to find bug out how a inconsistent potful affectthe results from a scenario set up in scientific environment. Theexperiment is to see how a certain variable will affect the gist ofGas produced from a atomic number 20 carbonate and Hydrochloric Acid Reaction.The ScienceCalcium change is a generally clean or colourless mineral that istranslucent. When compressed or exposed to long heat the mineralbinds together in small to large clumps forming atomic number 20 centuryateChips, however left in its formed state it is powder, a chalk likesubstance. I could use either forms of the Calcium Carbonate for theexperiment.Hydrochloric Acid, is a clear, colourless to slightly yellow liquidwith a sharp, snappy and irritating odour. It is a strong highlycorrosive sulphurous, soluble in water and alcohol but insoluble inhydrocarbons.The reason I am using Calcium Carbonate and Hydrochloric Acid for m yexperiment is collect to the reaction when they are put together. Afizzing reaction takes array letting loose Calcium Chloride, CarbonDioxide and Water.Word equivalence=============Calcium carbonate + Hydrochloric Acid === Calcium Chloride + Water +Carbon DioxideSymbol Equation===============CaCO3 + 2 HCl --- CaCl2 + H2O + CO2PredictionMy prediction is that if the concentration of the dose increases therewill be an increase in output of Carbon Dioxide from the reaction forexample the highest concentration produce the most gas in the given fourth dimension. I utilize a preliminary test to process in the prediction. I went andprepared marble chips and concentrated acid we act the experiment,the results was clear that as in a few seconds it was almost finished.When we used very dilute acid it took so long for it to react and theamount of bubbles were much less than the first one. By using theresults I can make the prediction of that, the rate of reaction isaffected by concentr ation. possiblenessIf the concentration of an acid increase than output of gas will as well asincrease. When the acid has a high concentration that means in thatsolution, compared to a dilute one there are more particles availableto react with therefore the amount of times they will collide with theeach other(a) is more.Factors-------There are many different factors, which effect the rate of reaction. infra is most of the known factors which effect the rate of areaction1. The coat of the particles of a solid reactant2. The concentration of the reactants solution3. Temperature of experiment4. Amount of time available for reaction5. Amount of solid reactant6. Amount of reactant solution soupcon sizeThe reaction between calcium carbonate and dilute hydrochloric acid is
