Compared to the pure water an aqueous solution of calcium chloride has a?
Higher boiling point and a lower freezing point. These are called colligative properties. When a solute is put into solution with the solvent, there is a change in the vapor pressure, osmotic pressure, elevation of the boiling point, and depression of the freezing point.
What is the vapor pressure of KCl?
Potassium chloride is a solid; the vapor pressure of solids is generally near zero.
At a constant pressure freezing occurs by what?
releasing energy
What affects freezing point?
The factors that affect the freezing point of water are 1. pressure : the pressure on the liquid may alter the freezing point. 2. impurities : the impurities in water such as salt, sugar etc also alters the freezing point.
Does calcium chloride raise or lower boiling point and freezing point of water at standard pressure?
The boiling point will increase with the addition of CaCl. I did an experiment where I added 13.002g of CaCl to 30mL of H2O and it raised the boiling point to 112oC. The initial reaction of CaCl and water produces heat in itself. The solution I used raised the water temperature to 75oC before the heat source was added to the water. I haven't experimented with the freezing point yet but I am assuming it will lower it because Calcium Chloride is an ionic salt and there is a tendency in ionic salts to lower the freezing point.
Is potassium chloride used in household salt to replace sodium chloride?
Yes, for people who have a sodium restricted diet due to high blood pressure, it is possible to substitute potassium chloride.
What has the author Virgil Bernard Sease written?
Virgil Bernard Sease has written: 'A study of the vapor pressure of aqueous solutions of potassium chloride at 20C ..' -- subject(s): Potassium chloride, Vapor pressure

Potassium chloride is a solid; the vapor pressure of solids is generally near zero.
What is lo salt used for?
LoSalt is a brand of low sodium salt. It is 66% potassium chloride and 33% sodium chloride. People replace their regular sea and rock salts with LoSalt when they have high blood pressure, which can be caused by too much sodium in the diet. Also, due to its potassium content, it can be used to supplement your potassium intake
Is potassium chloride ok to eat?
Yes. It is safe. It is used as an alternative to table salt, NaCl for people with high blood pressure or heart disease.
Main intracellular ion maintains icf osmotic pressure?
Potassium is the major intracellular ion, not sodium as was previously answered. Sodium is the major extracellular ion (along with chloride, and smaller amounts of potassium and bicarbonate)
How does pressure affect freezing?
Increasing pressure will give a lower freezing point. So if you wish to keep ice cold longer, increase pressure on the ice.
How pressure increases using sodium chloride?
This is the blood pressure.
What is potassium's normal phase?
At standard temperature and pressure, potassium is a solid.
Is freezing at -4 Celsius?
The freezing point of water is zero degrees Celsius at standard pressure.
What Mineral can increase blood pressure?
magnesium, potassium, and calcium
