Question 12

(Multiple Choice)

A membrane permeable by only Na+ separates two compartments containing Na2SO4,shown as follows: A membrane permeable by only Na<sup>+</sup> separates two compartments containing Na2SO4,shown as follows:   Electrodes are placed in both compartments,and a voltage is applied (that of compartment A is held at 0 mV).What voltage applied to compartment B would result in no net movement of Na<sup>+</sup> across the membrane separating the compartments? A)-60 mV B)-30 mV C)0 mV D)+30 mV E)+60 mV Electrodes are placed in both compartments,and a voltage is applied (that of compartment A is held at 0 mV).What voltage applied to compartment B would result in no net movement of Na+ across the membrane separating the compartments?
