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
What substances dissolve when added to a liquid?
all i know is that solutes lower its freezing point but i kinda think they dissolve into a liquid.
What is the freezing point of aluminum?
The melting and freezing points of an element are related, with freezing occurring below and melting being above that temperature. For aluminum, that point is 660.37 degrees Celsius.
How does adding salt affect the freezing point of water and what is the procedure of this experiment?
Adding salt (sodium chloride) the freezing point of water decrease; for an experiment add gradually salt (in known quantities) and measure the freezing point after each addition.
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 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.
Why does salt can melt a ice cube faster than pepper?
Because salt dissolves into water. The resulting mix (salty water) has a lower freezing point.Pepper does not dissolve into water.
Effects on freezing point when alum is dissolve in water?
The freezing point will be lower than water with nothing dissolved in it.
Will NaCl's affect the freezing point of a solution make the freezing point increase?
The freezing point of water solutions containing sodium chloride is lower.
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.
What substances dissolve when added to a liquid?

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.
Who will melt earlier benzoic acid or sodium chloride?
sodium chloride melt earlier because it has low freezing point
What effect does chloride salt have on water temperature?
Sodium Chloride- table salt - lowers the water's boiling and freezing point.
