An investigation in to the rate of reaction
Plan:
I am going to investigate the rate of reaction. The reaction I will be using is:
Calcium Carbonate + Hydrochloric acid ---- Calcium Chloride + water + carbon dioxide.

CaCO3 + 2HCl ---- CaCl +H2O + CO2

Measurements and Variables:
The variables I have chosen to change is strength of the hydrochloric acid which will be 1 mole, 0.7 mole, 0.5 mole, 0.3 mole and 0.1 mole some variable I will not be using are temperature, mass, density.
The measurements I will be using are time (s) and volume in (cm3).

Fair Test:
To make sure this a fair test I will get exact amounts of the Hydrochloric acid and Calcium Carbonate. I will also make sure that the Gas syringe is at zero when I start the experiment. I will also try and start the stopwatch as soon as I add the Hydrochloric acid.

Safety:
To make sure this will be a safe experiment I will make sure I wear goggles at all time. I will wash my hand immediately after the......
