Lowest freezing point liquid
WebAll the given solutions have the same molarity. The solution which has the lowest freezing point temperature is 0.1 M MgCl 2 . The solution which has the lowest freezing point temperature is one which has the highest depression in freezing point ( ΔT f ). The depression in freezing point is a colligative property and depends on the number of ... Web9 dec. 2013 · If you add enough salt, the freezing point of water can be dropped as low as -21 degrees Celsius. This fact means that water at -21 degrees Celsius can still remain liquid if enough salt is added. Instead of keeping liquid water from freezing, this powerful property of salt can also be used to turn ice back into water.
