Correct the following statements by changing the underlined part of the sentence (Do not change the whole sentence)
In a Galvanic cell, electrons flow in the external circuit from `ul("cathode towards anode.")`

Explanation

To correct the statement, we need to focus on the flow of electrons in a galvanic cell. Here’s the step-by-step solution:

1. **Identify the Components of a Galvanic Cell**: In a galvanic cell, there are two electrodes: the anode and the cathode. The anode is where oxidation occurs, and the cathode is where reduction occurs.

2. **Understand Electron Flow**: Electrons flow from the anode to the cathode in the external circuit. This is due to the fact that oxidation (loss of electrons) occurs at the anode, while reduction (gain of electrons) occurs at the cathode.

3. **Correct the Underlined Part**: The original statement says, "electrons flow in the external circuit from cathode towards anode." This is incorrect. The correct direction of electron flow is from the anode to the cathode.
