← ScienceWhich outcome occurs within a desalination plant utilising electrodialysis when the applied voltage drops?
A)Reduced selective ion migration rate✓
B)Enhanced oxidation near the anode
C)Increased water splitting at electrodes
D)Membrane fouling with organic matter
💡 Explanation
A lower voltage reduces the electric field strength, therefore the ions' migration rate decreases, limiting ion separation via electrodialysis, rather than enhanced oxidation, enhanced splitting, or organic fouling, because the voltage alone determines the drift speed.
