Question

Which reaction occurs at the cathode of a lead-storage battery that is being recharged?

Answer 1

@Kainui @nincompoop

Answer 2

Hmm, so it's being recharged, what does this mean in terms of voltage?

Answer 3

it should be going from a lesser to higher voltage right? @Kainui

Answer 4

You tell me.

Answer 5

I think I'm right haha

Answer 6

So it looks to me like you really only have 2 different reactions here since A and D are the same and B and C are the same, only reversed. So that might help you narrow it down.

Here's a nice picture

Answer 8

so in that picture it'd be the left beaker but how do I know the equation?

Answer 9

Why do you say it's the left beaker?

Answer 10

because the cathode has lead and it's being charged right..?

Answer 12

Nope, cause on the left you can see that the battery has a resistance on it, that's what it does when it's being used normally. But we're charging it up, which is the case on the right, which is the reverse reaction.

Answer 13

Oh ok I see... but I still don't know how to tell the reaction.
