The reaction that I will test the effect of concentration on is: Calcium + Hydrochloric Calcium + water + Carbon carbonate acid chloride dioxide Ca2+CO32-(s) + 2H+Cl-(aq) Ca2+Cl2-(aq) + H2O(l) + CO2(g) In order for this reaction to work the ions must all collide together with adequate force. The particles in calcium carbonate, in the form of marble chips, are held together by electrostatic attraction. The H+ ions and the Cl- ions in the acid (HCl) collide with the marble chips and break the bonds of calcium carbonate and the Cl- ions form a new bond with the oppositely charged Calcium to form Calcium Chloride. The 'Carbonate' is broken down into oxygen, which forms with the H+ ions forming water, and carbon dioxide is released. The rate of reaction depends on how many successful reactions there are. How long it takes to collect 100cm of carbon dioxide is used to test the effect of concentration of the rate...
