An investigation into how the concentration of hydrochloric acid affects the rate of reaction with marble (calcium carbonate) chips Introduction For the two substances to react the intramolecular bonds must first be broken by the activation energy. Once they are broken they need to collide with eachother to reform, with covalent bonds, to produce the new substances. In the case of hydrochloric acid and marble chips the basic reaction is shown below: Calcium Carbonate + Hydrochloric Acid = Water + Carbon Dioxide + Calcium Chloride CaCo3 + 2HCL = H2O + CO2 + CaCl2 For the reaction to take place activation energy is needed. The rate of reaction between the two substances is affected by many different factors. These include: * Temperature * Surface Area * Concentration/Pressure * Catalyst Aim My aim is to investigate how the concentration of hydrochloric acid affects the rate of reaction with marble chips Prediction I predict that as you increase the concentration of the hydrochloric acid...
