To make this experiment a fair test I will have to make sure the mass of the magnesium are the same, also make sure the surface area of the magnesium are the same. I have to make sure there is the same volume of hydrochloric acid in each beaker, and I have to make sure that the temperature is the same all the way threw the experiment. I also have to make sure the concentration of the acid is the concentration I say it is, because the concentration changes.
There are five concentrations in this experiment- 0.5m, 0.75m, 1.0m, 1.5m, and 2.0m. I am using five different concentrations because then there is a range from weak to strong, I am not going any higher in the
The simple explanation of this experiment is that the higher the concentration the faster the rate of reaction.
