During CO2 transport, HCO-3 diffuses from erythrocytes to plasma and in turn upsets the ionic balance momentraily. In order to keep the ionic balance, an equal number of Cl- pass into the erythrocyes from plasma. The process is known as

Answer:
chloride shift or Hamburger's phenomenon.
Explanation:
About 70% of CO2 is converted to bicarbonate ions (HCO-3 ) and transported in plasma. CO2 diffuses into RBCs, combines with-water and forms carbonic acid
(H2CO3). H2CO3 being unstable quickly dissociates Into H+ and HCO-3. HCO3−ions are quite diffusible. Therefore, HCO3− diffuses from RBCs into the plasma. To maintain the ionic balance CI− ions move from the plasma into the RBCs. This exchange is called chloride shift or Hamburger's phenomenon.
