Lab: Electrolytic Cells
Purpose: The purpose of this experiment is to test the method of stoichiometry in cells.
Wire lead (x2)
tin(II) chloride solution (3.25 M)
Take the mass of the steel can and record your observations.
I get 117.34 grams
Place the steel can in the large beaker.
Pour the solution of tin(II) chloride into the beaker so it surrounds (but does not go in) the steel can.
Place the tin electrode into the beaker.
Attach the wires to the steel can and the tin electrode.
Connect the wires to the proper terminus on the power source.
Set the timer to 6.00 minutes and start the timer.
The power source will come on automatically and will turn off automatically when time runs out.
Take the mass of the steel can.Assume it is completly dry when you do so.
I get 118.05 grams
What is the mass of the tin produced? Show all your work.
