Use the following diagram of a cell to answer questions -In the cell shown above,A is a standard Zn²⁺/Zn electrode connected to a standard hydrogen electrode (SHE).If the voltmeter reading is -0.76 V,which half-reaction occurs in the left-hand cell compartment?

Question

Quizplus · Accepted Answer

The voltmeter (F1F1F1S1F1F1F100.76 V) reading indicates that the left-hand cell compartment is the anode, where oxidation occurs (i.e. electrons are being lost). In choice B, Zn(s) is being oxidized to Zn²⁺(aq), releasing 2 electrons. This is consistent with the observation that the left-hand compartment is the anode. Therefore, choice B is the best choice. Choice A is the reverse of choice B, and the observation indicates that oxidation is occurring, not reduction.
