    ...........H2CO3 ==> H^+ + HCO3^-
    initial......x.......0.......0
    change..........2.51E-6..2.51E-6
    equil.......x-2.51E-6
    K = (H^+)(HCO3^-)/(H2CO3)
    Substitute and solve for x.
    Watch out. The H^+ from neutral water is 1E-7 and that's very close to this value. You may not be able to neglect that.
