Question

In cold climates, solutes are often spread on ice to make it melt. Sodium chloride (NaCl), calcium chloride (CaCl2), and glucose (C6H12O6) are all possible solutes. If you ignore all factors except which substance would lower the freezing point of water the most, which substance would be most effective? Answer choices:CaCl2 because it produces the most particles when it dissolves. NaCl because it is ionic. C6H12O6 because it is a molecular compound. Any substance that dissolves in water would work equally well.

Answer 1

NaCl because it is ionic.

Step-by-step explanation:

According to the question, solute are spread on ice in order to make it melt. The substance that would lower the freezing point of water the most is salt (NaCl) due to its ionic nature.

The more the ions that dissociate in the water, the lower the freezing point becomes.
