    No. The shifts in methanol and methanol/ water will be slightly different

    So the acid base peaks are only ones, besides solvent, that can change, when D2O is added to sample?

    SO42- needs a very high potential to be oxidized - so water is oxidized first.That's not much different from what is happening on the cathode in the presence of alkali metals - water reacts first (although for obvious reasons it is the other way around - reduction vs oxidation).

  • chemical that darkens when electrified

    Updated: 2013-01-31 08:29:59
    helloI'm working on this school project, and i want to build a welding mask, which automatically turns then when welding starts.problem is i don't know how to do this, so now I'm looking for a chemical that once electrified it either goes very dark (so dark you can weld with it) or opaque so you can see through.-and then switch between the two.in advance thanks!:)

  • Re: Alkylation vs acyl substitution of amide

    Updated: 2013-01-31 08:05:03
    That's pretty fruity. What's the amide, something active like an acyl pyrrole?Not the cheapest solution, but maybe try silver phenoxide - the Ag+ should strongly activate the alkyl bromide.You could also bulk up the amide.

  • Is lifting combat restrictions on women the achievement we need?

    Updated: 2013-01-24 16:35:52
    I am torn on the matter of Defense Secretary Panetta lifting restrictions on combat duties for women. I understand the rationale for greater upward mobility for women in the military. And I appreciate that women are already operating in combat areas. The point I want to offer is this:  rather than broadening the range of the population [...]
