When compared to pure water what will a 0.5 M solution of potassium chloride have a. lower boiling point b. lower freezing point c. higher capor pressure d. lower osmotic pressure?
b. lower freezing point A 0.5 M solution of potassium chloride will have a lower freezing point compared to pure water due to the presence of solute particles which disrupt the formation of ice crystals.
The difference between the boiling point and the freezing point of potassium is 695.72k What is the difference in degrees Celsius?
when converting to kelvin to celsius, subtract K by 273.15. The answer is 422.57 C.
Freezing point is the point at which a liquid turns into a solid What effect can change the freezing point?
Changing the pressure can affect the freezing point of a substance. Generally, an increase in pressure will lower the freezing point, while a decrease in pressure will raise the freezing point. The presence of solutes or impurities in the liquid can also change the freezing point.

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)

Why doesn't water freeze when potassium nitrate is in it?
Water DOES freeze when potassium nitrate is in it, it just doesn't do so as easily.Any solute will lower the freezing point of a solvent by a characteristic amount; for water it's 1.853 K kg/mol (that's Kelvins, kilograms of water, and moles of solute species; potassium nitrate is ionic and very soluble, so one mole of potassium nitrate will lower the freezing point of a kilogram of water by 3.7 Kelvins).This and similar effects are called "colligative properties", and the simplistic explanation is that the solute disrupts the ice crystal lattice ... essentially, it "gets in the way" of the water freezing.
When mercuric iodide is added to an aqueous solution of potassium iodide freezing point is raised why?
Freezing point of the solution will increase. Mercuric Iodide will react with Potassium Iodide to form dipotassium tetraiodomercury. The reaction is given below :2KI + HgI2 = K2[HgI4]This association will decrease the number of ions in the solution as a result of which Van't Hoff Factor (i) will decrease as n decreases from 4 to 3.Now, Freezing point depression when a solute is added to a solvent is given by ΔT = i Kf mClearly now i has decreased from when it was an aqueous KI solution to when HgI is added so ΔT is less now, hence less depression in freezing point which means a higher freezing point.Hence the freezing point of solution will increase.Note: Van't Hoff factor (i) =1+alpha(n-1) where alpha=dissociation degree and n is the no of ions dissociatedHope you understand the reasoning behind it now.
When should you apply rock salt?
Rock salt (or calcium chloride, potassium chloride) is applied to roads with ice or snow; the freezing point of water is lowered.
