How much would the freezing point of water decrease if 4 mole of Na Cl were added to 1 kg of water?
The freezing point decrease is -14,8 oC.
What happens to the freezing point of pure water when salt is added to it?
it lowers it. impurities lower the melting and raise the boiling point of substances. they also cause the melting point to fall over a range now. for example, water's melting point was initially 0 but upon adding salt it now is -5 to -1 degrees celsius.
Do additives affect how fast water freezes?
adding additives to water does effect the freezing point of water. When NaCl is added, it can effect it. Because the outside temperature isn't cold enough to keep the ice frozen inside.
What would the final freezing point of water be if 3 mole of sugar were added to 1 kg of water?
The CHANGE in freezing point can be determined from ∆T = imK where ∆T is the change in freezing point, i is van't Hoff factor (1 for sugar, a non electrolyte), m is molality (moles solute/kg solvent), and K is the freezing point constant for water (1.86). Thus ∆T = (1)(3)(1.86) = 5.58ºC. So, the FINAL freezing point will be -5.58ºC
Why The freezing point of salty water is less than that of pure water?
Depression in freezing point is a colligative property of solutions. When salt(solute) is added to the water(solvent), the vapor pressure of the water decreases. As a result, the freezing point of the water is lowered and hence salt water takes longer to freeze than pure water.

How much would the freezing point of water decrease if 4 moles of Na-Cl were added to 1 Kg of water?
The freezing point decrease is -14,8 oC.
How much would the freezing point of water decrease if 4 mol of sugar were added to 1 kg of water?
7.44 C

7.44 C
How much would the freezing point of water decrease if 4 mol of sugar were added to 1kg of water?
The normal freezing temperature for pure water is 0c. Howeverif sugar is added in the pure water, the freezing point will be lower than zero. How far below zero will depend on the sugar concentration in the water.
When urea is added to water the freezing point is decrease why?
This is a colligative property. Adding a solute will increase the boiling point and decrease the freezing point. The reason has to due with intermolecular forces, and interruption thereof. When water molecules have solute in between them, the temperature has to be lower than normal in order for them to freeze.

What does salt have to do with the freezing point of water?
Adding salt to water the freezing point decrease.
How does salt affect the water's melting point?
Adding salt to water the freezing point decrease.
What does salt do to an ice water bath?
The motivation is to decrease thr freezing point.
How much would the freezing point of water decrease if 4 mol of sugar were added to 1g of water?
Adding 4 mol sugar to 1 g (gram) water is impossible !
