Find pH from Total Alkalinity

  1. Apr 22, 2012 #1
    If given total alkalinity of a solution, and total carbonate concentration, is it possible to find the pH of that solution?

    Total alkalinity = [OH]- + [HCO3]- + 2 x [CO3]2- - [H]+

    Well,to check I guess you could see whether or not a hyrdogen ion would react with any of those alkaline materials because after all, the strict definition of a base is a proton acceptor...

    What about other things? Real water usually contains also other ions which are also included in the alkalinity.

    The hint: does saturation of the solution with carbon dioxide change alkalinity?
