Calcium Carbonate + Hydrochloric Acid Calcium Carbonate + Water + + Carbon Dioxide
CaCO3(s) + 2HC(aq) CaCl(aq) + H2O(l) + CO2(g)
The reaction between Hydrochloric Acid and Calcium Carbonate is being investigated because it produces a gas called Carbon Dioxide. This gas can be collected and is therefore a reliable result to base the investigation on.
Variable Why will this variable affect the rate of gas production?
Volume of HCl The more HCl used in this experiment would increase the rate of gas production, as there is more solution for the calcium carbonate chips to react with.
Concentration of HCl There are more reactant particles, therefore a greater chance of them colliding. So there are more collisions, increasing the rate.
Temperature of HCl The reactant particles are moving quicker and more particles have activation energy. There are more......
