Investigating the effect of acid concentration on marble chips Planning: The aim of this practical is to investigate the effect of varying acid concentrations on marble chips (CaCO3) 2HCL + CaCO3 --> CaCl2 + CO2 + H20 Hydrochloric Acid + Calcium Carbonate --> Calcium Chloride + Carbon Dioxide + Water Increasing the concentration of an acid increases the number of collisions between particles, therefore, the rate of reaction increases. The reaction will start faster in comparison to the speed at the end of the reaction. This is because when the two reactants are first mixed, their concentrations are both at their highest. As the experiment goes on, the concentration of the reactants will slow down, so the reaction will slow down until it finally comes to a stop. Constants: o The size of the marble chips - all the marble chips used will be 6mm in length. This is because the surface...
