Question

Use the information given below to answer the questions about this standard electrochemical cell.

ξo(V) Cu2+(aq) + 2 e- → Cu (s) + 0.34 Zn2+(aq) + 2 e-→ Zn (s) - 0.76

Mark each of these statements as True or False.

The electrons will flow from the cathode to the anode.

Positively charged ions flow from the salt bridge to the anode.

The solid metal cathode decreases in mass. Cu2+ is a reactant of this overall reaction.

The concentration of Cu2+ increases as the reaction proceeds.

Answer 1

Use the information given below to answer the questions about this standard electrochemical cell.

ξo(V) Cu2+(aq) + 2 e- → Cu (s) + 0.34 Zn2+(aq) + 2 e-→ Zn (s) - 0.76

1) The electrons will flow from the cathode to the anode.

False, because electron flows from anode to cathode

2) Positively charged ions flow from the salt bridge to the anode.

false

3) The solid metal cathode decreases in mass. Cu2+ is a reactant of this overall reaction.

False

4) The concentration of Cu2+ increases as the reaction proceeds.

False
