The solutions in the arms of a U-tube are separated at the bottom of the tube by a selectively permeable membrane. The membrane is permeable to iodine & potassium, but not to fructose. Side A is filled with a solution of 20g of fructose, 5g iodine, &60g potassium. Side B is filled with a solution containing 60g potassium, 10g of fructose, & 30g of iodine. Initially the volume of liquid is the same in both arms. Which direction would potassium pass through the membrane (DOK 3)? From Side B to A
Neither direction; the substance is not permitted to pass the membrane
From Side A to B
Back and Forth, between Side A and B ​
