Is freezing depression dependent on having a salt solute, or can non-ionic particles also have an affect on the freezing point of a liquid? Explain your thinking.

It is not dependent on the salt solute at all but the solute does have an affect.

Explanation:

in the equation you maybe aware of the I factor which represents the ions present in the solution. a non ionic will always have a I value of 1 a ionic can be 2 like in NaCl. What this means that all non ionic will lower the temperature  depression but ionics will have a greater affect because for example salt breaks into Na and Cl will essentially hae more impurities than glucose which doesnt dissociate and will have a I value of 1
