If calcium chloride is dissolved in water, what can be said about the concentration of the calcium ion? a. it has the same concentration as the chloride ion. b. its concentration is half that of the chloride ion. c. its concentration is twice that of the chloride ion.

b. Its concentration is half that of the chloride ion

Explanation:

As the calcium chloride formula is CaCl2

CaCl2 <--> Ca + 2 Cl-

in theory, limestone is composed principally of the compound calcium carbonate - caco3, but in reality this compound is deposited in conditions involving a number of other compounds as impurities so it ends up being a mixture of many compounds.
