# What Ion gets reduced in this aqueous electrolysis?

In an electrolysis of tin(II) iodide ($$\ce{SnI2}$$) with led cathode and nickel anode, why is it that the tin ion gets reduced and not the nickel ion?

• What nickel ion? – Buck Thorn May 27 at 9:05
• the nickel that gets oxidized – Pedro May 27 at 11:41
• ok, but if the nickel gets oxidized, and then reduced, there is no net reaction, right? – Buck Thorn May 27 at 12:38
• yes, this is from a school assignment. I did a similar one where there was no net reaction also but I understood why. In this one I dont know why one takes precedence over the other – Pedro May 27 at 12:41
• are you posting the full description of the problem? – Buck Thorn May 27 at 13:01
