(C) is correct option
Calcium carbonate contains which, if any, of the following ions? A. Ca+, CO3- B. Ca+2, CO-2...
the hardness of water causes the disolved Ca+2 ion form magnesium carbonate, Mg CO3 which is slightly doluble solids. soaking solid magnesium carbonate in water only yeilds small amounts of free calcium ion that can be captured but still solvated using a chelating milecule called Ethylendiamineteraacetic acid or EDTA. the 2 reactions involved: 1- Mg CO3 ➡ Mg^+2 + CO^-2 keq= 6.8×10^-6 2- Mg^+2 + EDTA ^-4 ➡ MgEDTA ^-2 + CO ^-2 keq= 4.90×10^8 these reactions combine to give...
