The answer is the membrane potential would remain the same due to the activity of the sodium-potassium pump. When a nerve or muscle cell is at "rest", its membrane prospective is called the resting membrane potential. In a representative neuron, this is about - 70 millivolts (mV). The minus sign specifies that the confidential of the cell is negative with respect to the neighboring extracellular fluid.
