← ScienceWhich outcome results when a high voltage is applied across a poorly conductive ionic solution?
A)Electrode polarization increases significantly✓
B)Ohmic heating decreases linearly
C)Ion mobility remains unchanged overall
D)Dielectric breakdown becomes less likely
💡 Explanation
When a high voltage is applied, electrode polarization increases dramatically due to the local accumulation of ions near the interfaces, hindering charge flow because of the build-up of local potential opposing main current. Electrode polarization increases, rather than heating decreasing or mobility remaining unchanged which would only happen if higher conductive solutions are used.
