Why is calcium chloride used to obtain dry ammonia …

Therefore, calcium chloride is widely used as a desiccant (humidity remover). So, streaming some gas through pellets of calcium chloride is an effective way to remove humidity from that stream. Still, many publiions provide the information that CaCl₂ cannot be used to dry ammonia , because apparently it forms a solid complex, CaCl₂.4NH₃ , with it.

1/1/1976· Calcium chloride offers many advantages that make it popular as a concrete accelerator. It causes a substantial increase in early strengths and it speeds rate of set. It is readily available. It dissolves easily in water.

Calcium Chloride in Portland Cement Concrete

produce a given slump when calcium chloride is used. Improves strength of air-entrained concretecalcium chloride compensates for the reduction in strength with a higher cement factor concrete. Reduces bleedingthis is due to the early stiffening

The chemistry of ferric chloride - Linda Goodman

Due to the low depth of bite necessary in aquatint, the strength of solution does not greatly affect time taken to create a black, therefore strength of solution tends to be a personal taste. The minus side is the length of time taken to bite a plate: half an hour in stock solution for a black aquatint, and an hour for an aver-age etched line.

Acceptable Use of Calcium Chloride in Concrete

allows calcium chloride as an accelerating admixture for cast-in-place concrete. But many specifiions prohibit its use. This is unfortunate because calcium chloride is the most efficient and least expensive accelerator used in concrete. It is particularly use

Calcium chloride in esterifiion???? | Bored Of Studies

7/5/2005· CaCl 2 is a dehydrating agent, meaning that it removes water formed during esterifiion: recall that esterifiion involves an acid reacting with an alcohol, and a water molecule is evolved when each unit of alcohol reacts with each uni of acid, and CaCl 2 is used to remove the water in your mixture, you can think of it as a way for purifying

Anodic and hodic Reactions in Molten Calcium …

18/7/2013· Calcium chloride is a very interesting electrolyte in that it is available, virtually free, in high purity form as a waste product from the chemical industry. It has a very large solubility for oxide ions, far greater than many alkali halides and other divalent halides and has the same toxicity as sodium chloride and also a very high solubility in water.

Using Fly Ash in Concrete

8/5/2010· This will increase the long-term strength of the concrete at a cost of slightly lower early strength. It is hard to give a precise strength estimate without knowing the details of your mix. However, high-quality fly ash will typically result in higher long-term strengths

Calcium Chloride for Home Cheese Making | Cheese …

8/9/2016· The beauty of calcium chloride is that it adds calcium ions to the milk and slightly raises the amount of acidity during the cheese making process (more about this below). And, because it strengthens the protein molecules in the milk, it boosts the yield of our cheese by as much as 2-3%.

Downs Cell for Sodium Production Chemistry Tutorial

Sodium chloride has a high melting point, ~800 o C, so calcium chloride or sodium carbonate is added to reduce the melting point to around 600 o C. The products of the electrolysis of molten (fused) sodium chloride are sodium metal and chlorine gas.

Calcium chloride - Wikipedia

Calcium chloride is used in concrete mixes to accelerate the initial setting, but chloride ions lead to corrosion of steel rebar, so it should not be used in reinforced concrete. The anhydrous form of calcium chloride may also be used for this purpose and can provide a measure of the moisture in concrete.
