Chloroform/metanol 1:1 turns cloudy when it is prepared!

  1. Sep 26, 2014 #1
    Hi!! I need to prepare Chloroform/methanol 1:1 and 1:2 and when I mix both solvents, it acquires a milky aspect. I have repeated the process several times in different flasks and bottles in the case it was due to wáter remaining or dirty stuff, but it always becomes cloudy when they are mixed. It has never happened to me previously. Could somebody help me! I am sorry but I am not good in Chemistry.. :(

    Perhaps one of the solvents contains impurities that are not soluble in the mixture?

    Both are 99% pure solvents from bottles just opened in that moment. That´s the reason why I am so concerned about.

    might be low solubility, and you're making an emulsion?

    Hm, I read her "It has never happened to me previously." as "I did in the past and it worked", but perhaps that's not what Laura meant.
