Salt is often used to melt ice on roads during the winter because it lowers the freezing/melting point of water.Based on what you have learned about the nature of chemical bonds and the properties of water,how does salt exert this effect?
A) When salt dissolves in water,individual Na+ and Cl- ions break away from the salt lattice and become surrounded by water molecules.Hydrogen bonds are broken,and the salt ions interfere with interactions between H and O.As a result,it is more difficult for water molecules to bond and form ice.
B) When salt dissolves in water,individual Na+ and Cl- ions break away from the salt lattice and become surrounded by water molecules.Hydrogen bonds are formed,and the salt ions bond with
H and O.As a result,it is more difficult for water molecules to bond and form ice.
