In much of the world, calcium chloride is derived from limestone as a by-product of the Solvay process. Calcium chloride can also be obtained from brine purification. Calcium chloride is not hazardous to the environment but classified as H319 according to GHS (causes serious eye irritation). ...

3 Calcium carbonate is insoluble in water. Sodium chloride is soluble in water.Which sequence of steps is used to obtain a pure, dry sample of calcium carbonate from a mixture of calcium carbonate and aqueous sodium chloride? D A filter→ dry the residue with filter paper → wash the ...
Increasing chloride densities in North American lakes could begin to upset local ecology and degrade sources of drinking water. Many local governments are looking for alternatives to rock salt. Other salts such as magnes...
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 pres...

Actually, I think I've understood what the OP and renge ishyo refers to: wikipedia says the the *pKa* of calcium chloride is ~ 8-9, not that the solution has such values of pH!!!http://en.wikipedia.org/wiki/Calcium_chlorideFor the OP: pKa = 9 means Ka = acidity constant = 10-...
It is very cold and saltiness would make it a very hard environment for any living thing. But the lead researcher, Professor Roberto Orosei from the Italian National Institute for Astrophysics, said it was not impossible for things to live there. ...
