<p>In the electroplating of nickel, .200 faraday of electrical charge is passed through a solution of NiSo4. What mass of nickel is deposited?</p>
<p>? g Ni = .200( 96,500 C / mole e-)(2 moles e-/1 mole Ni) (58.69 g/ 1 mole Ni)</p>
<p>this is wrong, I come out with an answer of 2.27 x 10^6, way too large, but maybe my proceedure will spark some1 else to realize the way this problem is actually solved?</p>
<p>Man, I cannot sleep before answering this one.</p>
<p>.200 Faradays = moles of e- flowing.
Since Ni2+ is become Ni solid, two electrons are moving per Ni, so .100 mol Ni.</p>
<p>But I am shaky as heck on this, so if someone could affirm or explain, PLEASE do so.</p>
<p>that’s definitely right. then multiply by the FW to get mass. you should come out with .5 ish. This is the 2004 multiple choice, right? I can’t believe i know that off the top of my head lol.</p>
<p>Man, why DO you know that off the top of you head?</p>
<p>I’m so woefully underprepared. =(</p>
<p>Haha, it did ask for mass, oops.</p>
