A solution containing one mole per litre each of Cu(NO_(3))_(2),AgNO_(3),Hg(NO_(3))_(2) and Mg(NO_(3))_(2) is being electrolysed by using inerty electrodes. The values of the standard oxidation potentials in vlts are Ag//Ag^(+)=-0.8V,Ag//Hg^(2+)=-79V,Cu//Cu^(2+)=-0.34V,Mg//Mg^(2+)=2.37V. The order in which metals will be formed at cathode will be-

Answer»

`Ag,Cu,Ag,MG`
`Ag,Hg,Cu,Mg`
`Ag,Hg,Cu`
`Cu,Hg,Ag`

SOLUTION :Metal having more VALUE of SRP will deposit first, but Mg does not DEPOSITION AQUEOUS solution.
