potassium chloride in water would be an impurity. When you add an impurity to a substance, you lower it's melting point. So adding potassium chloride to water would actually prevent the water from freezing.it is the same concept that the snow plows in Colorado use when putting Magnesium chloride on the road to keep them from freezing in the winter.

Adding potassium chloride to water will not make it freeze. It will lower the freezing point of the water.

Adding KCl lowers the freezing point, but without knowing the starting temperature, there is not enough information.

well you'd have to find the enthalpy of solution for KCl. and then add as much of it to lower the temperature the desired amount, although im not sure that you'd be able to dissolve that much into the water since KCl solution does have a saturation point.
