प्रश्न
Arrange the following according to the instruction given in bracket:
Cu2+, Na+, Zn2+, Ag+ (The order of Preferential discharge at the cathode)
उत्तर
Ag+ > Cu2+ > Zn2+ > Na
Explanation:
Increasing the ease of discharge
K, Na, Ca, Mg, Al, Zn, Fe, H, Cu, Ag
During electrolysis, the lower-position elements discharge more easily. The cation can easily accept electrons from the elements.
