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)
Which solution containing 1 mole of solute dissolved in 1000 grams of water has the lowest freezing point- KOH C2H5OHC6H12O6C12H22O11?
The lowest freezing point is observed for 1 mole of KOH, because its one moles produce 2 moles of ions in solution, 1 mole of cation K+ and 1 mole of anion OH-.
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.
Does alcohol have a freezing point?
it does have a freezing point it just contains a chemical that makes it hard to freeze
What is the freezing point of a solution that contains 0.550 moles of Nal in 615 g of water?
3.33 degrees Celsius is the freezing point of a solution that contains 0.550 moles of Nal in 615 g of water.

What is the freezing point of a solution that contains 2.0 mol of CaCl2 in 800.0 g of water Kf for water equals 1.86Cm?
2.0 mol of CaCl2 releases 2.0 mol of Ca+2 ions & 4.0 mol of Cl- ions = 6 moles of ions find molality: 6 moles / 0.800 kg water = 7.5 molal solution dT = kf (molality) dT = 1.86 C (7.5m) dT = 14 Celsius drop in freezing temp the new freezing point is - 14 C
How does the number of moles affect the freezing point?
Higher the concentration of the solute, lower is the freezing point.
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
When a solute is added to solvent the freezing point of the solution is?
The freezing point is lowered.
Which would lower the freezing point more 100 moles of sugar or 100 moles of NaCl?
100 moles of NaCl
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.
How do you solve freezing depression?
You need to know the solute and the solvent and whether the solute is molecular or ionic and how many ions it contains. The formula is the change in freezing point equals the number of ions times the freezing point depression constant times the molality of the solution.
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
Does alcohol have a freezing point?
it does have a freezing point it just contains a chemical that makes it hard to freeze
