What is the freezing point of a solution made by dissolving 352 g of ethylene glycol in 648 g of water?
The freezing point of the solution can be calculated using the formula: ΔTf = Kf * m. First, calculate the molality (m) of the solution by dividing the moles of solute by the mass of the solvent in kg. Then, use the molality and the freezing point depression constant (Kf) for water (1.86 °C/m) to find the freezing point depression (ΔTf). Finally, subtract ΔTf from the normal freezing point of water (0°C) to find the freezing point of the solution.

What is the Kf of ethylene glycol?
The freezing point depression constant (Kf) of ethylene glycol is 1.86°C/m.
What does ethylene glycol do to the solution in a vehicles radiator?
Ethylene glycol mixed up to 50% with water, lowers the freezing point of the mixture, while remaining an excellent heat transfer medium. It protects the engine from either freezing or from overheating.
The density of a 20 percent by mass ethylene glycol solution in water is 1.03gml Find the molarity of the solution?
To find the molarity of the solution, you first need to calculate the mass of ethylene glycol in the solution. Then convert it to moles using the molar mass of ethylene glycol. Finally, calculate the molarity by dividing the moles of ethylene glycol by the volume of the solution in liters.
Is antifreeze a pure substance or a mixture?
mixture
What colligative property is responsible for antifreeze?
The colligative property responsible for antifreeze is freezing point depression. Adding antifreeze (such as ethylene glycol) to water lowers the freezing point of the solution, preventing the liquid from freezing at lower temperatures.
What does ethylene glycol do to the solution?
Raises the boiling point and lowers the freezing point.
When ethylene glycol is added to water the boiling point of water is?
When ethylene glycol is added to water, the boiling point of the resulting solution increases. Ethylene glycol acts as an antifreeze, raising the boiling point and lowering the freezing point of water.
What is the Kf of ethylene glycol?
The freezing point depression constant (Kf) of ethylene glycol is 1.86°C/m.

Why in chemical terms is anti-freeze added to car windscreen wash?
Antifreeze is added to car windscreen wash to lower the freezing point of the liquid. This prevents the solution from freezing in cold temperatures, which can damage the system and obstruct vision during driving. Antifreeze typically contains chemicals like ethylene glycol or propylene glycol that are effective in preventing freezing.
Is ethylene glycol halal?
Ethylene glycol is not of animal origin !
What is the alcohol in antifreeze called?
The most basic / simplest is Methanol Useful alternative #1 is Ethylene Glycol Useful alternative #2 is Propylene Glycol There are also non-glycol, "Organic Acid Technology" (OAT) antifreezes used in some automotive applications.
Is antifreeze a colloid?
No, antifreeze is not a colloid. Antifreeze is a liquid mixture of chemicals, typically ethylene glycol or propylene glycol, that is used to lower the freezing point of water in automobile cooling systems. Colloids are mixtures where particles are evenly dispersed in a continuous medium, like milk or fog.
