At 1 AM, an impermeable membrane separates a 1 liter solution of 1M NaCl in the left compartment from a 1 liter solution containing both 1M NaCl and 1M KCl in the right compartment.
At 2 AM, the membrane became permeable to sodium ions. At 4 AM, the membrane became permeable to chloride ions and maintained its sodium ion permeability. The membrane maintained impermeability to potassium ions during the entire period.
A. The amount of sodium ions in the left compartment at 1 AM will be equal to the amount of sodium ions in the left compartment at 3 AM.
B. The amount of sodium ions in the left compartment at 5 AM will be greater than the amount of sodium ions in the left compartment at 3 AM.
C. The amount of chloride ions in the left compartment at 5 AM will be greater than the amount of chloride ions in the left compartment at 3 AM.
