Calculate the equilibrium concentration of H3O+ in the solution if the initial concentration of C6H5COOH is 6.0×10^-2. Kc=6.3 *10^-5

  • college chemistry -

    This is benzoic acid; let's call it HBz
    ..............HBz ==> H^+ + Bz^-
    initial......0.06.....0......0
    change........-x.......x.....x
    equil.......0.06-x.....x.....x

    K + (H^+)(Bz^-)/(HBz)
    Substitute and solve for (H^+).
