Will 1 mol of sugar have the same effect as 1 mol of table salt in lowering the freezing point of water?

no because the mol of sugar is 34 g while salt's mol is 5.8 grams

Which freezes faster out of salt water sugar water and tap water and why?
Assuming there are equal concentrations of salt and sugar in each sample, the sugar water will freeze faster. Salt dissociates into its ions when dissolved, giving two ions for ever salt molecule. Because freezing point depression depends only on concentration, and the concentration of ions is double that of the sugar, sugar will freeze faster.
What substance melts the fastest water juice or milk?
I would guess water. Sugar and salt, which are in greater amount in the other liquids, lower the freezing point, making things freeze slower and conversely melt slower.
Why do salt and sugar make ice melt?
Technically, they do not melt ice -- it requires heat to do that. But the addition of any solute (dissolved material) to water will lower its freezing point. So adding salt or sugar prevents melting ice from refreezing, or at least not until it gets much colder. The solute has the effect of blocking molecules attempting to form lattices in the water (ice), so it requires a lower temperature before the same number of water molecules can form crystals.
Can freezing be used to remove sugar from a mixture of water and sugar?
No it can't. you see sugar and water is a solution, so if you freeze it the sugar and water are still frozen together. You can't exactly evaporate sugar and you can evaporate water that's how you get separate the two. Thx.
What freeze faster sugar water or salt water or water?
sugar is a covalent compound where as salt is an ionic compound,so salt while dissolving in the water splits.This is mainly dependent of the 'total dissolved partical' concentration (mol/L):Sugar (C6H12O6): 1 mole particles per 180 g (for 1 mole sugar)Salt (NaCl) 2 mole particles per 58.5 g (for 1 mole salt) = 6 mole particles per about 180In water the freezing point will be lowered by 1.86oC per mole particles dissolved: So 180 g/L sugar: freeze at -1.86oCand 175.5 g/L salt freeze at -(6*1.86) = -11.2oCor 29.2 g/L salt will freeze at the same as 180 g suger: -1.86oC
What is the use of sugar in ice cream?
to be tasted Therefore sugar has two functions: Sweetening,Lowering the freezing point
Does sugar water boil at 100 degrees Celsius?
(At sea level) no. Sugar raises the boiling point as well as lowering the freezing point.
Why water mixed with sugar doesn't evaporate at 100c?
the sugar solution will not boil at 100C because the solute(sugar) has a slight attraction on the water molecules, increasing the boiling point and lowering the freezing point.
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 freezing point is lower for a saline solution.
Why does salt melt ice faster than sugar or sand?
Salt. Salt dissolves in water, and causes the freezing point to fall; this causes the ice to melt. Sugar does not have this effect, and chalk doesn't dissolve in water.
Does suger effect the freezing point in homemade ice cream?
Yes it does effect how fast it freezes because in the same way when you boil sugar and water the sugar is superheated but the water isnt, when you put it concentrated or not in the freezer then its the sugar that will mostly crystalize if they're's too much and it wil be dry or slimy or if you put too little sugar then it will be hard like ice and cream with a little sugar. People usually use the corn syrup or the brown sugar instead of granulated sugar.
Does freezing harm sugar?
No. Granulated sugar is crystalline and dry. Freezing will not effect it. There really is no need to freeze sugar as it will keep indefinitely in a dry area of your cupboard.
Does sugar the time it takes water to freeze?
The freezing point of solution is always less than that of the freezing point of the pure solvent. The freezing point of pure water is 0 (zero) degree celsius. The freezing point of the water decreases with the increase in the sugar concentration. for ex. a 10 grams of sugar when dissolved in 100 grams of water, the freezing point depression of -0.56 degree Celsius A 10 molal sucrose will bring about the depression in freezing point of water to about -20 degree celsius
What happens to sugar when put in water at freezing and boiling point?
Sugar lowers the freezing point of a liquid by a process called "freezing point depression". The same idea is used when salt is sprinkled on icy roads to melt the ice. Sugar only works half as well as salt however.
Does sugar effect the freezing points of water?
-25 degres The answer should depend on how much dissolved sugar per cc of water, and also a bit on what type of sugar it is. Also, even if it were spelled right, "-25 degres" doesn't mean anything until you specify what system is used. I think it might be close in the °C system, if the sugar solution were saturated.
Does sugar water affect the time it takes to freeze?
The freezing point of solution is always less than that of the freezing point of the pure solvent. The freezing point of pure water is 0 (zero) degree celsius.

Does sugar lower the freezing point of water?
Yes because of the sugar molecules and temperature.
