Re: freezing-point decreasing of potassium soap-surfactant-alcohol mixture « Reply #1 on: July 26, 2017, 05:09:07 PM » Hrm ...Ok. You have water with some solutes in it. They should lower the freezing point somewhat. Its hard to calculate for such a complex mixture, you should...
The freezing point of a liquid is the temperature at which that liquid transitions into a solid state. Water has a freezing point of 0° Centigrade, but ethanol has a freezing point of -114° Centigrade. This means that to freeze alcohol, you have to drop its temperature below -100° C...
