An investigation to find out how the concentration of acid affects the rate of the reaction between HCl and CaCO3 Skill Area P: Planning Experimental Procedures Introduction and Preliminary Work I am attempting to find out what affect the concentration of hydrochloric acid has on the rate of the reaction between HCl and marble chips (calcium carbonate). The equation of this reaction is as follows: CaCO3 (s) + 2HCl (aq) --> CO2 (g) + CaCl2 (aq) + H2O (l) calcium + hydrochloric--> carbon + calcium + water carbonate acid dioxide chloride There are many factors which can affect the rate of a reaction. The temperature of the acid will have an impact on how quickly a reaction occurs. I carried out a preliminary experiment on the affect of temperature as the variable, by using water baths and thermometers to obtain four different water temperatures in which the flask containing acid and marble chips was placed. I...
