Answer
equal to that of blood.
Reason — In dialysis, the osmotic pressure of the dialysis fluid should be equal to that of blood to prevent excessive movement of water either into or out of the blood. This ensures that waste products like urea and excess salts are removed without causing an imbalance in fluid levels or electrolytes in the body.
