Conclusions
The polytherms of the surface tension of solutions of K2Cr2O7, saturated at 20 and 25°, were studied. Close to the transition point of the solutions in the supercooled state, there is a discontinuity on the polytherm of the derivative of the surface tension with respect to the temperature.
