Homework Help: Anatomy & Physiology

  1. May 28, 2009 #1
    I'm a first year student Anatomy & Physiology and this really got to. I have been in Chemistry for about two weeks now and really need some help with this one.
    Questions is: Which of these is the pH of an acid solution?

    A. pH 7.1
    B. pH 7.0
    C. pH 12.4
    D. pH 6.9
    E. pH 8.3

    No Relevant equations

    The attempt at a solution was to guest after reading about chemical bonding, Elements and compounds, but when I got to pH it was a whole new subject, with the K+ CI-KCI I have know idea. Please help me.

    You are on the Calculus forum, but in answer to your question acidic solutions have a pH of < 7.

    Take a look at this wikipedia article, particularly the section titled Applications: http://en.wikipedia.org/wiki/PH.
    Freshly distilled water, which is neither acid nor alkiline, has a pH of 7.0. You should notice that one of your five choices is unlike the others, and is therefore the one you want.
