An investigation: Reacting magnesium with hydrochloric acid
Introduction
Experiment equation =
Magnesium + Hydrochloric acid Magnesium Chloride + Hydrogen
Mg + 2HCl MgCl2 + H2
The aim of the experiment is to investigate how the concentration of hydrochloric acid affects the rate of reaction with magnesium, i.e. how quickly/how much hydrogen is produced.
The factors that may affect the rate of reaction are as follows:
• Temperature of the Hydrochloric Acid
• Catalyst

The effect of temperature
is taking place, the particles move more quickly. This has two effects:
1) More collisions take place
lead to a reaction, because the activation energy is higher so the reactions will be more successful.
The effect of concentration
The concentration of a solution is how strong the solution is. In this leads to a greater frequency of collisions so the rate of the increases.
The Effect of surface area
increases the number of......
