Expert Answer:
In distal convoluted tubule, Na+ are reabsorbed actively and Cl- are reabsorbed passively into the blood. Absorption of water is controlled by ADH, which increases permeability of DCT to water. Absorption of Na+ is controlled by aldosterone hormone. Large amounts of water can be reabsorbed from collecting duct. So it should be permeable to water.
