What information is most useful to determine the solution that has a lower freezing point?
To determine which solution has a lower freezing point, you need the concentrations of solute in each solution and their respective properties (molal freezing point depression constants). The solution with the higher concentration of solute and lower molal freezing point depression constant will have the lower freezing point.
What solution which will not freeze at 0 degrees Celsius?
One solution that will not freeze at 0 degrees Celsius is a saturated salt solution, such as a solution of sodium chloride (table salt) in water. The addition of salt lowers the freezing point of water, preventing it from freezing at 0 degrees Celsius.
Why is the curve for the freezing of a solution different in slope from the freezing of the solvent?
The curve for the freezing of a solution is different from that of the pure solvent because the presence of solute particles lowers the freezing point of the solution. This phenomenon is known as freezing point depression. The slope of the curve for the solution is less steep than that of the solvent due to this depression effect.
Why does soduim ascetate turn into ice?
Firstly, when sodium acetate (CH3COONa) solidifies, it does not form "ice". It just becomes solid. This happens when the sodium acetate is heated to about 100oC, then cooled below its freezing point. When a foreign substance with the same crystal structure as sodium acetate is introduced, or a nucleation centre is provided, the sodium acetate will warm up to its freezing point and freeze at its (supposed to be) freezing point.
What effect does adding solute have on the freezing point of a solution?
the temperature at which the solution freezes is lowered.
Sodium bisulfite freezing point?
Sodium bisulfite does not have a fixed freezing point as it is a mixture of sodium metabisulfite and sodium sulfite. The freezing point can vary depending on the composition of the solution. Generally, a solution of sodium bisulfite will freeze at a lower temperature than water due to its composition.
How does the amount of salt in a solution affect its freezing point?
Increasing the concentration of sodium chloride in water the freezing point is lower.
What is the freezing point of water with 70000 ppm chloride?
A 7 % sodium chloride solution in water has a freezing point of -4,38 0C.
Will NaCl's affect the freezing point of a solution make the freezing point increase?
No, adding NaCl to a solution will actually lower the freezing point of the solution. This is because the presence of dissolved ions from the salt disrupts the formation of ice crystals, causing the freezing point to decrease.
Which one of the following aqueous solutions would have the highest freezing point: a solution of sodium chloride, a solution of glucose, or a solution of ethylene glycol?
A solution of ethylene glycol would have the highest freezing point among the three options.
What is the freezing point of the solution?
The freezing point of a solution is the temperature at which the liquid in the solution solidifies or freezes.
What is the process for using a salt water freezing point calculator to determine the freezing point of a solution?
To determine the freezing point of a solution using a salt water freezing point calculator, you need to input the concentration of salt in the solution and the calculator will provide you with the freezing point of the solution.
What is the freezing point of an aqueous 2.85 m sodium hydroxide NaOH solution The freezing point of pure water is 0.0ºC and Kf of pure water is -1.86ºC m?
-10.6 Celsius
What is the freezing point of an aqueous 2.85 m sodium hydroxide (NaOH) solution?
The freezing point of a 2.85 m sodium hydroxide (NaOH) solution would be lower than 0°C due to the presence of the solute particles, which depress the freezing point of water. The exact freezing point depression can be calculated using the formula: ΔTf = i * Kf * molality, where i is the van't Hoff factor, Kf is the cryoscopic constant, and molality is the concentration of the solution in moles of solute per kilogram of solvent.
Will a 0.5 M solution have a higher freezing point than a 0.75 M solution of the same substance?
No, the 0.75 M solution will have a higher freezing point. The freezing point depression is directly proportional to the molality of the solution, so a higher concentration solution will have a greater effect on lowering the freezing point.
What is the freezing point of a solution that contains 0.550 moles of Nal in 615 g of water?
The freezing point depression equation is used to calculate the freezing point of a solution. Given the molality of the NaI solution and the molecular weight of water, the freezing point of the solution can be determined.
When a solute is added to solvent the freezing point of the solution is?
The freezing point is lowered.
