What will be the freezing point change of the resulting solution if we dissolve 1 mole of aluminum chloride AlCl3 in 1000g of water?
∆T = imK∆T = change in freezing point i = van't Hoff factor = 4 because AlCl3 makes 4 ions m = moles/kg solvent K = freezing point constant for water = 1.86 ∆T = (4)(1m)(1.86) = 7.44 degrees C
In a solution of salt water is a physical property that salt maintains is?
In a solution of salt water, a physical property that salt maintains is its ability to dissolve in water, resulting in a homogeneous mixture. This solubility allows the individual sodium and chloride ions to disperse evenly throughout the water, leading to changes in properties like boiling and freezing points. Additionally, the presence of salt affects the density and conductivity of the solution.
What nontoxic solute requires the least concentration in volume with water to decrease the freezing point?
The nontoxic solute that requires the least concentration in volume to decrease the freezing point of water is sodium chloride (table salt). When dissolved, it dissociates into sodium and chloride ions, effectively lowering the freezing point through colligative properties. However, if considering a nontoxic option, sugar (sucrose) is often used, but it generally requires a higher concentration than sodium chloride to achieve the same freezing point depression. Thus, sodium chloride is typically more effective in smaller concentrations for this purpose.
Why is sodium chloride used to make freezing mixtures used by ice cream vendors?
Sodium Chloride when added to water helps reduce the freezing temperature of water, meaning that water will stay liquid at temperatures below it's actual freezing point of 0 degrees Celsius. Similarly, when sodium chloride is added to ice, the temperature of the mixture reduces rapidly and helps keep things cooler and ice creams are best when they're cold :) Hope this helps.
What salt is used in antifreeze to melt ice?
The type of salt commonly used in antifreeze to melt ice is calcium chloride. It has a lower freezing point than water, making it effective in preventing the formation of ice in freezing temperatures.
What effect does chloride salt have on water temperature?
Chloride salts dissolve in water without significantly affecting the temperature of the water. However, when chloride salts are used for de-icing roads or sidewalks, they can cause the surrounding environment to become colder by lowering the freezing point of water.

What is the freezing point of calcium chloride?
The freezing point of calcium chloride is around -50 degrees Celsius.
What is Freezing point liquid to solid of Aluminium and Stainless steel?
Aluminium 5000 liquid 2500 solid
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.
What is the freezing point depression of sodium chloride?
The maximal freezing point depression for sodium chloride is -18 0C. For the theoretical calculus see the link below.
Effects on freezing point when alum is dissolve in water?
The freezing point will be lower than water with nothing dissolved in it.
What would cause the greatest drop in a substance's freezing point... A. Barium Chloride B. Glucose C. Lithium Fluoride?
I suppose that barium chloride cause the greatest drop of the freezing point.
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 an aquerous 2.65m calcium chloride Solution?
-14.8 degrees Celsius
What in salt makes ice melt?
Salt is made up of Sodium Chloride (NaCl). In this case, it is the Chloride (Cl) that breaks the composition of water, and causes the freezing point of water to be lowered. Without Chloride, the freezing point of water is 32 degrees Fahrenheit (0 Celcius). With 10% of Sodium Chloride (salt), water freezes at 20 Fahrenheit. With 20% of Sodium Chloride, water freezes at 2 Degrees Fahrenheit.
