According to Hamburger phenomenon, when the whole blood is saturated with carbon dioxide, the following changes are seen (i) The bicarbonate contents of plasma and corpuscles increase. (ii) The chloride content of plasma is diminished and that of the cell is increased. (iii) The total base (cations) of both plasma and corpuscles remain unchanged. (iv) The water content and the volume of corpuscles increase. (v) When the carbon dioxide is removed from the blood reverse changes takes place. (vi) When ${\mathrm{CO}}_2$ enters blood, ${\mathrm{Cl}}^{-}$from plasma enters RBCs leaving ${\mathrm{Na}}^{+}$behind. When ${\mathrm{CO}}_2$ escapes from blood. ${\mathrm{Cl}}^{-}$leaves the cell and combines with ${\mathrm{Na}}^{+}$again. Due to this alternate movement of ${\mathrm{Cl}}^{-}$ ions, this phenomenon is called chloride shift.
