Why calcium chloride added in sodium chloride to lower the melting point?
The heat of dissolution for calcium chloride in water is greater compared with the same paremeter for sodium chloride; consequently the process of dissolution need more heat from the environment and the freezing point of the water solution is lower.
Why does the potassium permanganate diffuse faster than methylene blue?
Potassium permanganate diffuses faster than methylene blue because it has a smaller molecular size and lower molecular weight, allowing it to move more quickly through the medium. Additionally, potassium permanganate has a more polar nature compared to methylene blue, which can also influence its diffusion rate in certain environments.
What is the process of separating ammonium chloride from ammonium chloride and sodium chloride?
To separate ammonium chloride from a mixture of ammonium chloride and sodium chloride, you can dissolve the mixture in water to form a solution. Then, heat the solution to evaporate the water, leaving behind solid ammonium chloride due to its lower melting point compared to sodium chloride. This process is known as crystallization.
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.
Melting point of NaCl lower by the addition of calcium chloride?
Adding calcium chloride lowers the melting point of NaCl because it forms a eutectic mixture, where the two salts combine to create a lower melting point than either salt individually. This is due to the disruption of the crystal lattice structure of NaCl by the presence of calcium chloride.
When dichloromethane is mixed with water will the organic phase be in the upper level or lower level?
The organic phase, which contains dichloromethane, will be in the lower level when mixed with water. Dichloromethane is denser than water, so it will settle to the bottom layer due to its higher density.
What is the pH level of aluminium chloride?
Aluminum chloride is a strong acid with a lower pH level, typically around 2 or lower in its pure form. However, the pH of a solution containing aluminum chloride can vary depending on its concentration and any other substances present in the solution.
I need the cost of 6 uper extractions, 4 lower extraction.?
“I need the cost of 6 uper extractions, 4 lower extraction.”
Can a upper tooth extraction effect sinus?
Yes, the extraction of an upper tooth can affect the sinuses.

Can you use sodium chloride to lower pH level in pools?
I have never heard of it being used for that purpose and cant find any reference to it being used for that purpose. any acid would lower Ph however that does not mean that it wont have undesirable side effects.
How can salt be changed?
Normally the salt (sodium chloride) in a salt-water pool does not need changing. it does however need to be toped up once in a while to maintain the correct salt level for the chlorinator. However if the saltwater system is being changed to a Magnesium & potassium chloride system some water may have to be sacrificed to lower the sodium chloride level. it would be best to seek advice from chlorinator manufacturers on the technicalities in this case.
Why calcium chloride is added with sodium chloride in metallurgy of sodium?
Calcium chloride is added to sodium chloride in the metallurgy of sodium because it helps lower the melting point of the mixture, making it easier to separate sodium metal from the molten mixture. This lower melting point allows for better efficiency in the electrolysis process.
Which separating technique is suitable for ammonium chloride and sodium chloride?
Sublimation - on gentle heating ammonium chloride will sublime. Sodium Chloride does not and has a high melting point.
Why is water lower than the melting point of sodium chloride?
Sodium chloride is a ionic compound. Generally they have high melting points.
Why calcium chloride added in sodium chloride to lower the melting point?
The heat of dissolution for calcium chloride in water is greater compared with the same paremeter for sodium chloride; consequently the process of dissolution need more heat from the environment and the freezing point of the water solution is lower.
What effect does the anhydrous calcium chloride have on the air in test tube?
It dries it - in other words, it removes the moisture from the air.
