Planning: How the Concentration of Hydrochloric acid Affects the Rate of Co2 produced by Marble chips Introduction: From this experiment I hope to succeed in finding the answer to the to the question: How does the amount of concentration of hydrochloric acid affect the amount of carbon dioxide given off by the reaction of calcium carbonate (marble chips) and the acid. I know that the following reaction takes place when the acid and chips are united: Hydrochloric acid + calcium carbonate ? Calcium chloride + water + Carbon dioxide This is how I know Carbon dioxide is produced but how much with different concentrations of acid is the question. Diagram: Variables: Input variable: Concentration of hydrochloric acid Output variable: Amount of Carbon dioxide produced Constant variables: Temperature (room) Mass of marble chips Volume of acid/water (50cm3) Surface area of marble chips Method: I will set up the apparatus as shown in the diagram but without the marble chips in, then...
