Question

look at the diagram of an electrochemical cell below. which statement describes what would take place if oxidation were to stop? A) reduction would continue on one electrode. B) readings on the voltmeter would increase. C) electrons would not flow through the voltmeter. D) ions would continue to flow through the salt bridge.

Answer 1

i put c

Step-by-step explanation:

Edge doesnt give correct answers on unit tests, but i passed with an 88 :)

Answer 2

Answer : The correct option is, (C) electrons would not flow through the voltmeter.

Explanation :

Electrochemical cell : It is defined as a device used to convert the chemical energy produced in a redox reaction into electrical energy. The redox reaction taking place.

The electrode on which the oxidation takes place is called the anode (or negative pole) and the electrode on which the reduction takes place is called the cathode (or positive pole). This cell is setup by using the salt bridge.

In the external circuit, the electrons flow from the anode (negative pole) to cathode (positive pole) through the voltmeter. In the inner circuit, the ions flow through the salt bridge.

From the given diagram, we conclude that when the oxidation will be stop then the electrons would not be flow from anode (negative pole) to cathode (positive pole) through the voltmeter.

Hence, the correct option is, (C) electrons would not flow through the voltmeter.
