Question

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

Explanation:

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

Answer:

A. Reduction occurs at the cathode.
