In this video we will be growing some tin crystals using a stannous chloride solution and some electrolysis. Music by Kevin Macleod. I forgot the song though... Stannous chloride: https://www.youtube.com/watch?v=zziLOly2R8U EDIT: It was pointed out by KotMatvej that the solution doesn't actually boil, but it is electrolytic sides reactions which are producing gas. These are the two side reactions that he suggested: 2Cl- -- 2e = Cl2 2H2O - 4e = 4H+ + O2 This was an oversight on my part and
