Question

Explain why freezing occurs faster in plain water compared to salt water and sugar water

Answer 1

One thing I know, salt reduces the freezing temperature of water, its why ppl use salt on snow and ice. Not because it melts it, but because it reduces the freezing temp.

Answer 2

Adding anything to a pure substance [such as water] decreases that substances freezing point; therefore, a lower temperature is required to freeze that substance. Pure water reaches it's freezing point before salt and sugar water do.
