Question

where does oxidation occur for a galvanic or voltaic cell? oxidation occurs at the anode. oxidation occurs in the salt bridge. oxidation occurs at the cathode. oxidation occurs across the voltmeter.

Explanation:

In a galvanic (voltaic) cell, the anode is the electrode where oxidation takes place (loss of electrons), while reduction occurs at the cathode. The salt bridge is for ion migration to maintain charge neutrality, and the voltmeter measures voltage, not where oxidation occurs. So oxidation occurs at the anode.

Answer:

A. Oxidation occurs at the anode.
