Anhydrous calcium chloride is often used as a dessicant. In the presence of excess of CaCl2, the amount of the water taken up is governed by Kp=6.4×1085 for the following reaction at room temperature, CaCl2(s)+6H2O(g)⇌CaCl2.6H2O(s). What is the equilibrium vapour pr...

Isoflurane, also known as isoflurane, is an inhaled general anesthetic drug that is an isomer of enflurane. Isoflurane is a colorless and transparent liquid with a special fragrance. The blood/gas distribution coefficient is small, the anesthesia induction is smooth, rapid and comfortable, the reco...
it should be stored under dry conditions to prevent violent reactions with moisture or other water- or alcohol-containing substances. Adding an appropriate amount of desiccant, such as anhydrous calcium chloride or silica gel, to the storage container can help adsorb the surrounding moisture and main...
odor and a mild taste. Insoluble in cold water, can be dispersed in hot water to form a milky solution. It can be dissolved in hot oil and various organic solvents to form a milky solution. The freezing point is 45~47℃, and the HLB value is 6.7. Sorbitan monopalmitate is used in...

The conventional quality of anhydrous isopropanol is more than 99%, while the special grade isopropanol content is higher than 99.8% (for flavors and drugs). In many cases, isopropanol can substitute ethanol as the solvent and is a good solvent and chemical raw materials which can be applied ...
Calcium chloride (anhydrous) molecular weight is 110.98 g/mol, so (following the maths in the post) to get 1000ppm (as CaCO3 equivalent) you need 110.98 ÷ 100000 × 1000 ~= 1.11 g per litre. If you have a solution with 1gr/10ml then you therefore need 11.1ml of your solution, then...
