Why Is Nickel Losing Electrons in Electrolysis?

[RJLiberator]

Okay, so that is the master.chem problem that I am struggling with.

I feel I understand what's going on... Nickle is the anode that should be losing two electrons. What am I doing wrong according to mastering chemistry?

I feel this is an issue with how I am writing things? Or am I missing the point here.

Thanks

I see nothing wrong about your logic.

Damn, is it possible that I am messing up the states of the metal? =/

 

[Borek]

No, states look OK as well.

Just occurred to me - why do you assume M to be divalent?

 

[RJLiberator]

That's a very good point. However, when I do M^n+ + ne^- --> M(s)

it gives me the response of:

"

Sorry, can't help you with the mastering chemistry - all I know is that people hate its quirks when it comes to input formatting.

M^n+(aq)? M^{n+}? M^{n+}(aq)? Space after comma? Just M^+?

Is there some other information given that could help decide about Mⁿ⁺ charge?

Wow, how lame - what they wanted as the metal reaction to be defined as Ni^2++2e^--->Ni instead of as Metal.

I have no idea how that works out, but whatever.

Thank you very much for confirming my thought process. Cheers.
