The topic report will consist of all background information on tin can corrosion and galvanic cells with reference to the variables pH and surface area. The Research Questions and Hypothesis have already been decided on and created in an earlier post, but I will include them again for reading conveniences. Below you will find the Aim, Method and Equipment with a diagram of the setup of the Fe and Sn galvanic cell.

Research Question

What effect will the pH of the solution within a galvanic cell and surface area of metals have on the rate of corrosion?

Hypothesis
It was hypothesized that as the pH decreased and the surface area increased within a Fe and Sn galvanic cell then the corrosion rate of the Fe would increase when the amount of solution, type of container, multimeter, temperature and type of joint are kept constant.

Aim
To investigate the effect that pH of the electrolyte solution and surface area of electrode have on the corrosion rate of Fe in a Fe and Sn galvanic cell when type of container, amp meter, temperature and type of joint are kept constant. 

Equipment

• Tin Metal
• Iron Nails
• 6x 250mL Beaker
• 1M HCL
• Tin Chloride in solution (SnCl)
• Iron Chloride in solution (FeCl)
• Multimeter
• Sodium Chloride (NaCl)
• Paper Towel
• Safety Glasses
• Gloves
• Lab Coat
• Blu-Tack

Method
The method will appear at a later date as the electrolyte solutions will need to be mixed up.

Below is a diagram of the setup of the Galvanic Cell I have made on Word.
