Question

Freezing mixture is a mixture which produces a very low temperature. State whether true or false.
a) True
b) False

Answer 1

Hint: The freezing point is the temperature at which liquid transforms into a solid state. A freezing mixture is a compound that produces a shallow temperature. The statement is accurate because it is a mix-up of ice, water, salt, dry ice, or alcohol, providing very low temperatures.

Complete step-by-step solution:
A freezing mixture is a composite of two or more elements. It is utilized to obtain a temperature below the freezing point of a solvent. The principle behind it is the depression in freezing point.
A freezing Mixture is a mix of salt and ice. It is used to lower the temperature. A compound of dry ice and alcohol can also be utilized for this. A freezing mixture will not receive heat from the external.
The freezing point is that temperature at which liquid transforms into a solid state. For example, NaCl is a non-volatile substance, and it is called salt. When we combine salt with ice, it will first diffuse in the liquid. So, it will decrease the freezing point of water beneath the temperature of ice. So, ice will soften when we combine salt and ice, and extra water will be formed. So, this will assist in dissolving more salt. Freezing mixtures are utilized in labs for Cooling. The freezing compound can be solid, liquid, or both. For example, a compound of dry ice with alcohol can also be utilized as a freezing mixture. They can reduce the temperature up to $-{80}^{\circ }C$.
The statement is true.
Option (a) is true.

Note:Colligative property involves depression in freezing point. Freezing point depression is the reduction of the freezing point of a solvent on the joining of a non - volatile solute. E.g., alcohol in water. For example, one of the freezing mixture's importance is putting salt on cold roads during the winter. As a result, the melting point of ice will be decreased, and that makes driving safer.
