Hydrochloric Acid and Marble Pieces In my investigation I will be testing how changing the concentration of the Hydrochloric acid makes an effect and changes the speed of the reaction. I will do various experiments and then evaluate the results and come to a conclusion. The reaction that will take place is Hydrochloric acid + Calcium Carbonate Calcium Chloride + Water + Carbon dioxide Hypothesis The more concentrated the acid then the quicker the reaction will take place, because there will be more HCl particles than water particles for the marble chips to collide with and therefore react. More collisions between the two reactants (HCl and CaCO ) will take place resulting in a quicker time for the reaction. If the temperature at which the reaction takes place is increased then the reaction will be faster because the particles will have more energy and therefore collide more often. The increase in surface area will result in a...
