Rate of reaction when acid concentrations are varied This experiment is to find out does the rate of reaction change when the acid concentration is increased or decreased when reacted with marble chips. Introduction Marble chips, when reacted with hydrochloric acid forms calcium chloride, water and carbon dioxide (Marble chips can also be called limestone or calcium carbonate) Normal equation 2HCl (aq) + CaCO3 (s) ® CaCl (aq) + H2O(l) + CO2 (aq) Ionic CaCO3(s) + 2H+(aq) ? Ca2+(aq) + CO2(g)+ H2O(l) Word Hydrochloric acid + Calcium carbonate®Calcium Chloride + Water +Carbon dioxide The experiment can be controlled by a few factors, these affect the rate of reaction Factors Mass of chips - How much chips or how little chips. If there were more chips, the experiment will react longer Concentration of acid- How many moles/dm³ there is in the acid. If the concentration is high, the rate of reaction will increase. Temperature- The higher the temperature there will be a...
