Answer #1

The reduction potentials (how likley they are to REDUCE)

Cu2+ + 2 e− is in equilibrium with Cu(s) +0.337

Zn2+ + 2 e− is in equilibrium with Zn(s) −0.7618

Mg2+ + 2 e− is in equilibrium with Mg(s) −2.372

Ag+ + e− is in equilibrium with Ag(s) +0.7996

then, if we want the OXIDATION strneght, we must invert every set

Cu(s) is in equilibrium with Cu2+ + 2 e− -0.337

Zn(s)is in equilibrium with Zn2+ + 2 e−  +0.7618

Mg(s) is in equilibrium with Mg2+ + 2 e− +2.372

Ag(s) is in equilibrium with Ag+ + e− -0.7996

the most easy to oxidize will be Mg

the least will be AG

Hardness in groundwater is due to the presence of metal ions, primarily Mg2 and Ca2 . Hardness is generally reported as ppm CaCO3. To measure water hardness, a sample of groundwater is titrated with EDTA, a chelating agent, in the presence of the indicator eriochrome black T, symbolized here as In. Eriochrome black T, a weaker chelating agent than EDTA, is red in the presence of Ca2 and turns blue when Ca2 is removed. Red blue Ca (ln)2+ +EDTA------->Ca EDTA...
