An investigation of the effect of concentration change on the rate of the reaction between magnesium and hydrochloric acid.
Title
The title of this piece of coursework is 'An investigation of the effect of concentration change on the rate of the reaction between magnesium and hydrochloric acid'.
Aim
I am going to investigate the relationship between the concentration rate of Hydrochloric acid and Magnesium reaction.
Summary
In this experiment, I will us different concentration rate of hydrochloric acid to react with magnesium and discover the time it takes to complete the reaction.
I will also use three states of magnesium. Ribbon turning and powder, to see if there is any influence on the timing if different states of magnesium are used.
I will take a few measurements during the experiment:
. How long it takes to release a certain amount of gases?
2. What is the maximum amount of gas produced in 7 minutes?
3. Compare the different of reaction rate of 3 states of magnesium?
Procedure
I have to set the quantity of the amount of magnesium and the volume of hydrochloric acid, so I have done a TEST RUN before I do the practical test.
Amount of magnesium
At first, I have set the amount of magnesium as 1 gram. However, I found that it is impossible to do it in the experiment. It is easy to get 1 g of magnesium in chip state, but in ribbon state, it is about a few metres long because the ribbon is thin. Also, it will take ages for it to react with the acid.
Eventually, I set the amount of magnesium as 0.1 gram because the reaction will not take too long and the length of the magnesium ribbon is appropriate.
Volume of hydrochloric acid
The volume of the hydrochloric acid cannot be too low because it needs to cover the whole part of the magnesium so that it is a fair test and accurate result so that I have set the volume of hydrochloric acid to 20ml.
