The presence of sugar (or salt, or any other dissolved substance in water) does indeed lower the freezing point of water. This phenomenon, called freezing point depression, occurs because the particles of the dissolved substance interfere with the formation of the crystalline bonds between water molecules that give ice its solidity.
Interestingly, the addition of a solute (dissolved substance) to water not only lowers the freezing point but also raises its boiling point – a phenomenon referred to as boiling point elevation. It does this by lowering the vapor pressure of water (a tendency that describes a substances tendency to turn into a gas).
The vapor pressure, boiling point, and freezing point of water (or a solution containing water and another substance) are referred to as colligative properties – properties that depend on the amount of the solute in a solution.

Water freezes at 32 degrees Fahrenheit (0 degrees Celsius), but when a solute such as sugar is added, the freezing point changes. The sugar molecules prevent the water from making hydrogen bonds, which are required for solidity, and the water has to become even colder before it reaches its freezing point.
The temperature at which a liquid turns into a solid is known as its freezing point. In theory, the melting point of a solid should be the same as the freezing point of the liquid. For example, at 32 degrees Fahrenheit (0 degrees Celsius), there is an equilibrium between water freezing and ice melting. Molecules of ice are melting, and molecules of water are sticking to the ice and becoming frozen at the same time. The water looks frozen at this point.
When you add sugar to water, the water (the solvent) becomes a solution (a solute dissolved in a solvent). Adding sugar disrupts the liquid state because sugar molecules move around aimlessly, making the liquid water molecules less organized. Sugar molecules dont pack together with water molecules, so when the water molecules start to freeze, the sugar molecules remain in the liquid water. When the water molecules create ice, the sugar molecules have a smaller volume of liquid in which to move.
Sugar particles are able to dissolve only in a liquid solvent and wont dissolve when the solvent is in a solid state. Therefore, adding sugar to water lowers the chemical potential of the solution, which also lowers its freezing point. In other words, a solution of sugar dissolved in water must be cooled to a lower temperature than the pure solvent in order for freezing to happen. When the freezing point of a liquid is lowered by the presence of an additive, freezing point depression occurs. The exact freezing point is determined by the quantity of solute particles dissolved in the solvent. The more solute particles there are in the water, the greater the freezing point depression of the solution.
A water molecule consists of one oxygen atom and two hydrogen atoms. Temperature measures how much energy is created by moving molecules. When water molecules are cold, they don’t have a lot of energy, so they don’t move around a lot. Instead, they move together and form hydrogen bonds to create a solid structure called ice.

FAQ
Does sugar affect water freezing point?
Does water freeze faster with salt or sugar?
What happens if you put sugar in water and freeze it?
What makes water freeze faster?
Does sugar freeze if added to water?
Instead sugar will drop the freezing point (freezing temperature). Pure water freezes at 0º Celsius, but when you add sugar to that, it will freeze at lower temperatures such as -5º C or -8ºC. Original version of this experiment required students to have a thermometer and measure the temperature when the solution starts to freeze.
Is there any truth to the claim that water can quickly lower blood sugar?
Yes, drinking plenty of water can help dilute the blood sugar. Thus, consuming water helps with glycemic control and blood hemoconcentration.
Why does sugar affect the freezing point of water?
Water freezes at 32 degrees Fahrenheit (0 degrees Celsius), but when a solute such as sugar is added, the freezing point changes.
Does sugar freeze at 0°C?
What sugar really does is not delay in freezing. Instead sugar will drop the freezing point (freezing temperature). Pure water freezes at 0º Celsius, but when you add sugar to that, it will freeze at lower temperatures such as -5º C or -8ºC.
