Need help with solutions and pH

  1. Feb 11, 2012 #1
    Hi there, I was wondering if anyone could help me with 3 questions:

    1) Without pH papers, how do you calculate the pH of a 5% H2SO4 (sulfuric acid) solution?
    I know vinegar is a weak acid, but would a 5% acetic acid have the same pH of a %5 H2So4 solution?

    2) If a non-polar solvent such as Hexane is miscible with Ethanol, does that mean that they mix completely? If so, would the water traces from the alcohol stay at the bottom below the Hexane layer?

    3) H202 (Hydrogen peroxide) is an oxidizing agent just like Permanganate. I need to replace the later, is it possible to dilute or concentrate Peroxide in order to make it work like Permanganate?
    Besides one begin stronger than the other, what other differences are there between these oxidizing agents? :confused:

    Thanks :biggrin:

    gee 300 views and no one has a clue on this school chemistry? :confused:
    and it's not homework, just something I've always wondered
