The following four solutions are kept in separate beakers and copper metal is put in each of them. Which solution will become blue after some time ?
AgNO3 solution
Zn(NO3)2 solution
Ba(NO3)2 solution
NaNO3 solution
A.
AgNO3 solution
The element, placed above in electrochemical series, can replace the elements (placed below) from their solution. Here copper is placed only above silver (Ba, Zn and Na are placed above Cu). Hence, it can replace Ag from its salt solution. Thus, solution becomes blue due to Cu2+ ions.
Cu + 2AgNO3(aq) + 2Ag
