Oxidizing and Reducing Agents - Purdue University

The permanganate ion removes electrons from oxalic acid molecules and thereby oxidizes the oxalic acid. Thus, the MnO 4-ion acts as an oxidizing agent in this reaction. Oxalic acid, on the other hand, is a reducing agent in this reaction. By giving up electrons, it reduces the MnO 4-ion to Mn 2+.. Atoms, ions, and molecules that have an unusually large affinity for electrons tend to be good ...

Membrane Potential – Foundations of Neuroscience

Predict Ion Movement by Comparing Membrane Potential to Equilibrium Potential. It is possible to predict which way an ion will move by comparing the ion's equilibrium potential to the neuron's membrane potential. Let's assume we have a cell with a resting membrane potential of -70 mV. Sodium's equilibrium potential is +60 mV.
