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.

∙ 13y agoThe freezing point (strictly the melting point) will be depressed by a degree or so Celsius. The ice will float. Ice is not a good conductor of heat, so the water below the ice will tend to stay ice free. Which the fish consider to be a GOOD THING.

∙ 11y agoAdding salt to water lowers its freezing point. The freezing point is lowered because the chemical potential of the solution is lowered, making this state more energetically favorable even at somewhat lower temperature.

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 grit is added?
That really depends what you mean by grit. If it's just powdered rock, there is no effect. If you mean rock salt, then the freezing point is reduced because the salt dissolves. The lowest freezing point achievable for salt solution is - 21.1 degrees C.
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.
Which ionic compound will lower the freezing point the most of 1 mol of it is added to 1 mol of it is added to 1 L of water?
NaCl
What happens to water when antifreeze is added to it?
The boiling point increases and the freezing point decreases.
When antifreeze is added to water the freezing point of the water is what?
It drops to about 12 degrees Fahrenheit.
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.
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 decreases 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 altitude increases what happens to the freezing point of fresh water?
it rises

Water freezing in bottle when opened?
Water freezing in bottle when opened happens in the case of supercooled water. This water has been cooled below freezing point without being crystallized.
What occurs when NaCl is added to water?
The boiling point of the solution increases, and the freezing point of the solution decreases.
What happens if you mix salt with water?
The freezing point of the water is lowered. ADD: You get a salt water solution.

Why does the freezing point of water lower when solute is added?
the solute gets in the way of the water turning to ice
