Do you know a website where I can find this equation? (disposition of tin)? I have searched through many webpages but got no information
No, I don't; however, look at your set up (the one you posted giveing the procedure) and you will see it staring you in your face. You used SnCl2 as the electrolyte and you used a piece of Sn in the bottom of the steel can.
