At 1 AM, an impermeable membrane separates a 1 liter solution of 2M KCl 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 potassium ions. At 4 AM, the membrane once again became impermeable to potassium ions. At 6 AM, the membrane became permeable to chloride ions and, in addition, maintained potassium ion impermeability. At 8 AM, the membrane became permeable to potassium ions again and, in addition, maintained its permeability to chloride ions. The membrane stayed impermeable to sodium ions at all times.
A. The amount of chloride ions in the right compartment at 9 AM will be greater than the amount of chloride ions in the right compartment at 7 AM.
B. The amount of chloride ions in the right compartment at 7 AM will be equal to the amount of chloride ions in the right compartment at 5 AM.
C. The amount of potassium ions in the right compartment at 9 AM will be greater than the amount of potassium ions in the left compartment at 9 AM.
