Drawing cell diagrams y13

In a cell diagram which is written on the left

egZn(s)∣Zn²+(aq)||Cu²+(aq)∣Cu(s)

• Oxidation

• Reduction

In a cell diagram a single line | represents a 

• a salt bridge

• a change in phase

• two chemicals in solution

• an inert electrode

Two parallel lines || represent

• A salt bridge

• a phase change

• an electrode

• two chemicals in solution

Where can the electrodes through which the electrons flow be found in a cell diagram?

• Next to the salt bridge

• between the ||

• at the ends of the cell diagram

• In the middle of the cell diagram

Which are the electrodes in this cell diagram?

Zn(s)∣Zn²+(aq)||Cu²+(aq)∣Cu(s)

• Zn²+ and Cu²+

• Zn(s) and Zn²+(aq)

• Cu²+(aq) and Cu(s)

• Zn(s) and Cu(s)

In this cell diagram which are the two electrodes?

Fe(s)∣Fe2+(aq)∣∣MnO4−(aq),Mn2+(aq)∣Pt(s)

• Fe2+ (aq) and Mn2+

• Fe(s) and Pt(s)

• MnO4−(aq) and Fe2+(aq)

• Mn2+ and MnO4−(aq)

In this cell diagram which is oxidised and which is reduced?

Fe(s)∣Fe2+(aq)∣∣MnO4−(aq),Mn2+(aq)∣Pt(s)

• Fe2+ (aq) ox and Mn2+ red

• Fe(s) ox and Pt(s) red

• Fe(s) ox and MnO4−(aq) red

• Mn2+ ox and MnO4−(aq) red

In this cell diagram why is there a comma?

Fe(s)∣Fe2+(aq)∣∣MnO4−(aq),Mn2+(aq)∣Pt(s)

• to show a phase change
