In this paper, the unsteady MHD free convective flow through porous medium sandwiched between electrically conducting viscous-incompressible fluids in a horizontal channel with heat and mass transfer, with the assumptions that the upper and lower channel are non-porous (clear regions) and the middle channel as porous respectively have been studied. The governing equations of the flow were transformed to ordinary differential equation by a regular perturbation method and the expression for the velocity, temperature, and concentration for the flow were obtained. It is observed that the fluid velocity decreases with an increase in Prandtl number, Radiation parameter, Hartmann number and Schmidt number. Some of these governing parameters had little effect on the velocity profile while others had significant effect on this velocity profile. The same was seen on the temperature profile and concentration profile. Finally the governing parameters had effects on the flow and this study does aid in the practical usage of such flow or when confronted with such a flow.
