High-schooler here reading up on electrochemistry..... I came across this equation (and its derivation) in the book *Physical Chemistry*, by Wallwork and Grant: [![enter image description here][1]][1] [![enter image description here][2]][2] [![enter image description here][3]][3] Now the thing is, the equation is valid for '*uni-univalent*' electrolytes (like KCl). But I want a more....'versatile' formula. So I attempted to modify that equation to suit electrolytes of the type **AB** (i.e- magnitude of charge on a formula unit cation is equal to that of the charge on a formula unit anion). I wrote down the whole thing (my formatting skills are terrible, so to *type* it out would be a HUGE pain in the neck), pardon the handwriting, I hope it's legible enough.... [![enter image description here][4]][4] [![enter image description here][5]][5] [![enter image description here][6]][6] As for that last question.....I was wondering if the equation could be made *even more* 'versatile' 3:) ( @getafix don't think of me as clingy but...I'm counting on you for this one too! ) [1]: https://i.sstatic.net/hPUIW.jpg [2]: https://i.sstatic.net/t0x2v.jpg [3]: https://i.sstatic.net/JLqgF.jpg [4]: https://i.sstatic.net/T5Ik2.jpg [5]: https://i.sstatic.net/32avk.jpg [6]: https://i.sstatic.net/EzOiB.jpg
