For electrolysis of concentrated NaCl solution, which of the following will be anode?

• Cl-

• OH-

• H+

• Na+

Write an equation for the spontaneous reaction.

• Sn2+ (aq) + Ni (s) → Sn (s) + Ni2+ (aq)

• Sn+ (aq) + Ni (s) → Sn (s) + Ni2+ (aq)

• Sn2+ (aq) + 2Ni (s) → Sn (s) + Ni2+ (aq)

• Sn2+ (aq) + Ni (s) → Sn (s) + Ni+ (aq)

In a voltaic cell utilizing a copper electrode and a zinc electrode, which electrode serves as the anode?

• Copper electrode

• Zinc electrode

• It depends on the concentration of the electrolyte

• Neither electrode

In an electrolytic cell with a solution of silver nitrate (AgNO3), if both silver ions (Ag+) and hydrogen ions (H+) are present, which ion will preferentially undergo reduction at the cathode?

• Silver ions (Ag+)

• Hydrogen ions (H+)

• Both ions undergo reduction equally

• It depends on the concentration of each ion
