What is the freezing point of an aqueous 2.65 m calcium chloride CaCl2 solution?
-14.8
What happens when anhydrous calcium chloride is exposed to the atmosphere for about 2 days?
Calcium chloride absorb easily water and become a hydrate; after some time, being hygroscopic and deliquescent, solid calcium chloride is transformed into a solution.
What is the formula of anhydrous calcium chloride?
CaCl2
What is the use of anhydrous calcium chloride in the experiment of rusting of metals?
Calcium chloride is a water absorbant.
How do you Dispose of anhydrous calcium sulfate?
If present in aqueous solution, by precipitating using sulfuric acid and obtaining insoluble calcium sulphate.
After making standard calcium chloride solution how you can adjust the 1ml equals 1 mg of calcium?
It all depends on the type of Calcium Chloride you used. Was it anhydrous or dihydrate or else?
What is the balanced chemical equation for the reaction of aqueous calcium chloride with aqueous sodium carbonate to produce calcium carbonate precipitate in an aqueous sodium chloride solution?
The chemical reaction isȘCaCl2 + Na2CO3 = CaCO3 + 2 NaCl

Why does a nail not go rusty if its in anhydrous calcium chloride?
The nail would not go rusty because it was kept dry and the anhydrous calcium chloride removed the moisture from the air

What are formulas for calcium chloride and patassium phosphate?
Calcium chloride has the formula CaCl2 if anhydrous. Potassium phosphate has the formula K3PO4.
What ions are present in what ratio in a solution of aqueous calcium chloride?
The ions are: Ca2+ and Cl-; the ratio chloride ions/calcium ions is 2.
What substance can be use to dry hydrogen gas?
