And so what happens is these bicarbonate ions will move down their concentration gradient and into the red blood cell. And at the same time, the chloride shift takes place, but in the opposite direction. So as we move these bicarbonate ions into the red blood cell, not to have a build up or a change in electric charge, these chloride ions, also containing a negative charge, are basically pumped to the outside into the blood plasma space. And once we bring these bicarbonate ions into the sound, the hemoglobin basically releases those H plus ions. And the H plus ions now combined with the bicarbonate to form back this. So this actually should have this should be H two.
