Re: Oxidation Numbers for Sulfur in H2S4

I see, thank you! ChenBeier is spot on correct! :lol: But here's some rules of thumb and tips regarding oxidation numbers that I found helpful when I was learning way back when...I still use these today when tutoring/teaching chemistry to others! :!: Rules for assigning oxidation numbers: The oxida...

Re: About mixed solvent system used in chromatography

ChenBeier is absolutely correct - with a solvent mixture you are able to collect a large array of different molecules. I'm not sure exactly what else you're question entails, but I've tried to focus in only on information pertaining to what you originally posted: why mixed solvents can be used in c...

Re: Determine the equilibrium constant

I think it's just a minor oversight. You seem to have left your reaction at the "midway" point, because most equations that contain negative coefficients result in some kind of mistake or incorrect answer due to the initial reaction not being properly or fully balanced. The first equation...

Re: Determine the equilibrium constant

996.6 is also similar as 1097,84 also not accurate to 1000. The general Nernst Equation : E = Eo -(RT/nF)lnQ where: Eo = standard electrochemical cell potential (voltage) R = ideal gas constant T = temperature n = moles of electrons F = Faraday constant = 96,485 C mol-1 Q = mass-action expression (...
