What is the change in the boiling point and freezing point of 500 grams of water if 45 grams of glucose C6H12O6 were dissolved in it?
This quantity is equivalent to 90 g glucose / kg water = 0.50 mole particles of solute / kg water, so with a 'molar cryoscopic constant' for water of -1.86 oC/kgthis lowers the freezing point to -0.93 oC.
Which has a higher freezing point a 20 percent salt solution or pure water?
Pure water has a higher freezing point than 20% salt water.
What happens to the freezing temperature of a solution of table salt in water as the solution becomes more concentrated?
As concentration of a solute (like table salt) in a solvent increases, the freezing point of water lowers. The vapor pressure also decreases, and the boiling point increases. These are known as water's colligative properties.
Does solute effect the freezing point of water?
the temperature at which the solution freezes is lowered.
What effect did the addition of sugar to Beaker B and salt to Beaker C have on the freezing point of the water in these beakers?
The addition of sugar to Beaker B lowered the freezing point of the water, while the addition of salt to Beaker C also lowered the freezing point of the water. This is because both sugar and salt act as solutes that disrupt the formation of ice crystals and reduce the freezing point of the solution.
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 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.
What is the change in the boiling point and freezing point of 500 grams of water if 45 grams of glucose C6H12O6 were dissolved in it?
This quantity is equivalent to 90 g glucose / kg water = 0.50 mole particles of solute / kg water, so with a 'molar cryoscopic constant' for water of -1.86 oC/kgthis lowers the freezing point to -0.93 oC.
Which solution containing 1 mole of solute dissolved in 1000 grams of water has the lowest freezing point- KOH C2H5OHC6H12O6C12H22O11?
The solution with glucose (C6H12O6) would have the lowest freezing point. This is because the number of particles in the solution contributes to the lowering of the freezing point, and glucose, being a covalent compound, dissociates into more particles in solution compared to the other compounds given.
21.6 g NiSO4 in 1.00 102g Hu2082O what is the freezing point of this solution?
To determine the freezing point of the solution, you need to calculate the molality of the NiSO4 in the H2O solution. Once you have the molality, you can then use the formula for freezing point depression to find the freezing point. This formula is ΔTf = Kf * m, where ΔTf is the freezing point depression, Kf is the freezing point depression constant (for water it is 1.86 °C kg/mol), and m is the molality of the solution. Finally, add the freezing point depression to the normal freezing point of water (0°C) to find the freezing point of the solution.
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.
Is salt water colder than fresh water?
The freezing point of salted water is lower than the freezing point of pure water; this is a phenomenon known as freezing point depression when a solute exist in the solution.
What occurs when NaCl is added to water?
The boiling point of the solution increases, and the freezing point of the solution decreases.
What would be the final freezing point of water be if 3 mol of sugar were added to 1 kg of water?
-5.58 C
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.
What is the freezing point of water with a 5 percent salt solution?
The freezing point of water with a 5 percent salt solution is lower than the freezing point of pure water. The exact freezing point will depend on the type of salt used, but typically it will be around -6 degrees Celsius (21.2 degrees Fahrenheit).
What is the freezing point of this solution 21.6 NiSO4?
The freezing point of a solution depends on its concentration and the properties of the solute. For a NiSO4 solution, the freezing point will be lower than that of pure water, but the exact value would require additional information such as the concentration of NiSO4 in the solution.
