The dynamics of an impurity ion of charge q_{0} embedded in a two-component ionic plasma is represented as that of a particle in a random medium. The effect of the surroundings on the impurity is represented by a memory function whose form is proposed in this work. Our choice stands for the strongly coupled plasma for which the memory function has an oscillatory behavior with the plasma frequency. The model therefore describes the plasma in the strong coupling limit. We first derive a master equation governed by this memory function and, with the help of the Laplace transform, we solve it via a quartic algebraic equation. We calculate in the end the dynamical properties, i.e. the autocorrelation functions which are very useful in many areas of plasma physics as in radiative transport and in spectral line shape broadening theories.
