Question

based on what youve learned about what happens when water freezes, which of the following helps explain why road salt is added in the winter to help prevent ice from forming on roadways and sidewalks?
correct answer(s)
salt disrupts the crystal lattice by getting between the water molecules.
salt generates covalent bonds with water and prevents freezing.
since salt is polar, it dissolves in water and disrupts hydrogen bonding.
salt causes the water molecules to vibrate and heat up.
incorrect answer(s)

Explanation:

When salt is added to water, it dissolves as it is polar. It gets between water molecules, disrupting the crystal - lattice formation during freezing and also disrupts hydrogen bonding. Salt does not form covalent bonds with water and does not cause water molecules to vibrate and heat up in the context of preventing ice formation.

Answer:

Salt disrupts the crystal lattice by getting between the water molecules.
Since salt is polar, it dissolves in water and disrupts hydrogen bonding.
