An impermeable membrane separates one liter of a 1M KCl solution in the left compartment from one liter of 1M NaCl solution in the right compartment. At 2 AM today the membrane became permeable to chloride ions only. At 4 AM today the membrane became permeable to sodium ions and maintained its chloride permeability.
A. The amount of chloride ions in the left compartment at 5 AM is equal to the amount of chloride ions in the left compartment at 3 AM.
B. The amount of sodium ions in the left compartment at 5 AM is equal to the amount of sodium ions in the right compartment at 5 AM.
C. The amount of sodium ions in the right compartment at 5 AM is less than the amount of sodium ions in the right compartment at 3 AM.
