What is the freezing point of potassium hydroxide?
48% KOH freezing pt -11deg C 45% KOH freezing point -28 deg C The change in freezing point (always a decrease) = (number of ions in solution per molecule) x (Kf - the freezing point constant of the solvent) x (m - the molality of the solution, i. e. moles solute per kg solvent) For KOH in water, Freezing pt = 0 - 2(1.86)(molality of solution)
The solution has a freezing point of -2.79 . The freezing point depression constant for water is 1.86 K m-1. What is the nitrate concentration in the solution?
The solution has a freezing point of 2.79 and this is the frezzing point of mercury
What colligative property is responsible for antifreeze?
Freezing point depression. When a solution is formed the molecules of the solute prevent the solution from freezing at its normal freezing point, it must be colder.
What lowers the freezing point and raises the boiling point?
Yes, it is possible if the solution contain solutes.
When a solute is added to solvent the freezing point of the solution is?
The freezing point is lowered.
Will a 0.5 M solution have a higher freezing point than a 0.75 M solution of the same substance?
Will a 0.5 M solution have a higher freezing point than a 0.75 M solution of the same substance?
Is nitrogen an element compound solution or heterogeneous mixture?
Nitrogen is an element.
Is N2 a pure substance or a solution?
Nitrogen (N) is a chemical element, not a solution; nitrogen can be obtained as a very pure gas.
By which method do we get a pure soid from a solution?
We can get a pure solid from a liquid by freezing the solution.
What effect does solute have on the freezing points of the solution?
the temperature at which the solution freezes is lowered.
The freezing point of a solution containing 4.12 g of unknown solute in 100 grams of camphor is 166.2 degrees C what is the freezing point depression?
f.p depression = (freezing point of pure solvent)-(freezing point of solution) -------> 178.4-166.2=12.2
What effect does adding a solute have on freezing point on a solution?
the temperature at which the solution freezes is lowered.
