Why Does Water Not Freeze at 0°C When Either Ions

question 117

Multiple Choice

Why does water not freeze at 0°C when either ions or molecules other than O are present?

• A)Molecules or ions dissolved in the water give the water molecules something else to easily bond with, thus allowing the solution to freeze well above 0°C.
• B)Molecules or ions dissolved in the water increase the number of water molecules at the solid-liquid interface, thus allowing for the rate of ice formation to increase at a temperature above 0°C.
• C)When molecules or ions are dissolved in the water, these solute molecules both take up space and inhibit the formation of the solid phase, thus lowering the freezing point temperature below 0°C.
• D)Molecules or ions dissolved in the water will sometimes raise the freezing point above 0°C and other times lower it below 0°C depending on the nature of these solute particles.
