Rate of reaction of hydrochloric acid on magnesium.
The first 200 words of this essay...
Science Coursework: Rate of Reaction
The Aim of the experiment:
In this experiment I will investigate the relationship between the concentration of the hydrochloric acid and the rate of a reaction. To find this out I will react different concentration of hydrochloric acid and magnesium, from there I will monitor the gas (hydrogen) produced and analyse the results.
I predict the higher the molarity of the hydrochloric acid the faster the rate of reaction therefore the quicker the gas will be produced in the specific time interval.
Overview of the experiment:
In this reaction two substances will be present in the solution, magnesium and hydrochloric acid. During the reaction magnesium particles will collide with the hydrochloric acid particles to produce the salt Mg chloride and hydrogen gas. The amount of gas will be monitored at certain time intervals to find out the rate of reaction. However I will be changing the molarity of the HCl by diluting it with water. The water molecules will prevent the Mg and HCl particles to collide, this is because the water molecules will get in the way of the collisions therefore providing an obstacle for the two
