Demonstration of the Rates of Reaction Between Sulphuric Acid (25mL ±0.5mL) and Magnesium (0.02g ±0.01g) Changing Due to Different Surface Areas
By Chania Baldwin
Introduction:
When sulphuric acid and magnesium are added together, magnesium sulphate and hydrogen gas is created. To create such a reaction the atoms must collide with a sufficient amount of energy. Every reaction requires a different amount of energy to create the reaction, which is called the activation energy; when there is not enough activation energy the particles simply bounce off of each other in an elastic collision. When new molecules are produced by the success of the collision with activation energy, it is called ‘activated complex’.
This investigation is being carried out to test if the rate of reaction between 25mL of sulphuric acid and 0.02g of magnesium will increase or decrease when the surface area of the magnesium varies, when the mass stays the same.
In this investigation the sulphuric acid will have a tube connected to it and to a measuring cylinder filled with H2O (see images 1 and 2). This is to visibly see when the reaction between the sulphuric acid and the magnesium happens, because the gas created from the reaction will push the water out from the measuring cylinder and into the bucket it is connected to (again, refer to images 1 and 2 for visual aid). Once the water has been pushed to the 25mL reading on the measuring cylinder the time is stopped and the reaction is measured.
This is what will happen in the investigation, and why the investigation is taking place is to see if the surface area will have an effect on the rate of reaction.
Research question/statement:
The purpose of the experiment is to test if the surface area of magnesium will affect the rate of reaction when added to 0.8M sulphuric acid. The changes of the independent variable will affect the dependent variable because the surface area will have an affect on the possibility for particle collision which
