Chlorides | AMERICAN ELEMENTS
Chlorides are compounds that contain chlorine along with a more electropositive element. The chloride form of any metal is generally soluble in water, with the exception of lead chloride, which is only slightly soluble, and silver chloride, which is insoluble. Antimony chloride, bismuth chlorides, and others decompose in water to create oxychlorides. Most metal chlorides can be melted without

thresholds for sodium chloride and calcium chloride in water are in the range 200–300 mg/litre (2). The taste of coffee is affected if it is made with water containing a chloride concentration of 400 mg/litre as sodium chloride or 530 mg/litre as calcium chloride (3).
Calcium - Simple English Wikipedia, the free encyclopedia
Calcium is a chemical element. Its syol on the periodic table (a list of all the elements) is Ca. Its atomic nuer is 20. (The atomic nuer says where Calcium sits in the periodic table.) It has 20 protons and 20 electrons (if is an atom, see ion). The most common isotopes are Ca-40 and Ca-44. Its mass nuer is about 40.08. Calcium is
