Question

Which of the following statements is NOT correct about the Galvanic cell shown below?

a. The voltage and current can be made to do useful work.

b. The voltage measured by the voltmeter is 1.1 V under standard conditions.

c. By means of the connecting wire metallic zinc can give electrons to copper ions which become copper atoms.

d. Negative charge leaves the zinc side through the wire as electrons.

e. Charge neutality is preserved on the zinc side through the salt bridge either by negative ions moving in or positive ions moving out. Thus, there is no build up of positive charge as the electrons leave.

f. Negative charge enters the copper side through the wire as electrons.

g. Charge neutality is preserved on the copper side through the salt bridge either by negative ions moving out or positive ions moving in. Thus, there is no build up of negative charge as the electrons enter.

h. Thus, the salt bridge is necessary for the galvanic cell to work.

i. The salt bridge is not necessary for the galvanic cell to work.

ELECTROCHEMISTRY (GALVANICOR VOLTAIC CELLS) External circuit 2 Half-Cells Voltmeter Copper f SALT BRIDGE-Any medium through which ions can slowly pass CI It allows electrical contact between the two solutions. It prevents mixing of the electrode Solutions. Electrode It maintains electrical neutrality in each half-cell as ions flow into and out of the salt bridge. Agar. A gelatinous material derived from algae and used as a thickener

Explanation / Answer

Hi

All the above statements about the galvanic cell is true except

i. The salt bridge is not necessary for the galvanic cell to work.

as, salt bridge is really necessary to maintain the charge neutality.

Thank you
