%X The dispersion relation of an ion-acoustic wave propagating through a collisionless, unmagnetised plasma, having warm isothermal electrons and cold positive and negative ions has been derived. It is seen that the ion-acoustic wave will be unstable in the presence of streaming of ions. Instability of the wave is graphically analysed for the plasma having (H+, O&#175;) ions, (H+, O2&#175;) ions, (H+, SF5&#175;) ions, (He+, Cl&#175;) ions and (Ar+, O&#175;) ions with different negative ion concentration and relativistic velocity.
