Which statement about electrochemical equilibrium is true? For a given ion concentration gradient, the resulting potential is independent of the rumber of charges on the ion At least one ion has to have equal concentration inside vs. outside The size of the potential is inversely proportional to the size of the ion gradient R occurs when the potential across the membrane exactly offiets the movement due to the concentration gradient
