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 an overall reaction:
3- Mg CO3 +EDTA ^-4 = MgEDTA^-2 + CO ^-2 keq3= ?
a. is reaction 1 product favored or reactant favored?
b. is reaction 2 product faverod or reactant faverod?
c. determined the new equiliburim constant?
d. is teaction 3 product faveroed or reactabt faveroed?

Experiment 8 Name: Double Replacement Reactions Background: Some reactions have the net effect of causing the cation of cach reactant to trade places, forming a compound with the other anion. These reactions are known as double replacement reactions. In the example below (unbalanced equation), the barium and sodium cations switch places so that barium forms a product with sulfate while sodium forms...
