А stable glow discharge was produced in atmospheric air using water solutions as a cathode. It was fond the quenching current of the discharge depends on the solution nature. We found out the dependence between the quenching current and ballast resistance, geometry of the discharge gap. The quenching current depends strongly on the concentration of the solution. It was fond the existence of two forms of the dis- charge. In our opinion the difference of the quenching currents in the same conditions is the consequence of the deformation of the current-voltage characteristic.
