PlanAimI am doing this experiment to find out how I can speed up the reaction rate between calcium carbonate and hydrochloric acid. EquipmentThis is the equipment I leave al cardinal use&61623 Gas Syringe&61623 Glass Flask&61623 Calcium carbonate&61623 Hydrochloric AcidVariable FactorsThe factors that could slow down or speed up this reaction ar&61623 The coat of the Calcium Carbonate ( stain) pieces This pass on incite how fast the acid reacts with the marble, the smaller the pieces, the bigger the surface area so the reaction can take place instant(prenominal).&61623 The amount of Calcium Carbonate The more than calcium carbonate there is, the more carbon dioxide pass on be produced and the bigger the reaction allow for be.&61623 The amount of Hydrochloric Acid The more hydrochloric acid there is, the more carbon dioxide forget be produced and the larger the reaction will be.&61623 The temperature of the materials The temperature of the materials determines how fast the reaction will take place. The hotter the materials, the scurrying the reaction and vice-versa. &61623 The concentration of Hydrochloric Acid The higher the concentration (strength) of the acid, the faster it will react. &61623 The purity of the Calcium Carbonate pieces The purity of the calcium carbonate will affect the speed of the reaction also.PredictionFrom previous experiments I acquire learned that if large pieces are blue into smaller pieces they react faster because they have more surface area. This is because at the molecular level, there are more molecules at the surfa ce of the chips for the molecules of acid to react with when the chips are broken into smaller pieces. The same principle can be applied to the marble chips. The smaller the chips the more surface area so I foreknow that the smaller marble chips will react faster than the larger chips.MethodHere is the set upIn this experiment I will be keeping the variables I mentioned earlier the same except one to keep the experiment fair. I will be changing the size of the marble chips to see which size reacts the fastest. The gas syringe is firstly clamped to the brave and a plastic tube and bung are attached to the syringe.
