Rate of Reaction between CaC03 and HCL Aim In this experiment I have the choice to change any variable to see what effects it could have. I am changing the temperature of the hydrochloric acid to investigate the rates of which the Calcium Carbonate reacts with it, and to discover what amount at which temperatures release a more quantity of gas (carbon dioxide). The other variables I could choose from to investigate are: · Size of the Calcium Carbonate Chips. · Concentration of the hydrochloric acid- · How weak or strong it is. · The temperature of the acid. · Surface area of the conicle flask. · Amount of chips. · Amount of Hydrochloric acid. The Equation. Calcium + Hydrochloric (r) Calcium + Water + Carbon Dioxide. Carbonate Acid Chloride The Chemical Equation CaCo (s) + 2HCl (aq) (r) Ca Cl (aq) + H O +Co (g). Prediction I predict that as the temperature rises, the average Speed of particles increases. At high temperatures, there are...
