Carbon dioxide is transported in the blood from the tissue to the lungs in three ways:1 (i) dissolved in solution; (ii) buffered with water as carbonic acid; (iii) bound to proteins, particularly haemoglobin. Approximately 75% of carbon dioxide is transport in the red blood cell and 25% in the plasma.
Chlorine has 7 valence electrons in its outer shell and needs 1 more electron to get a complete octet. Chlorine will not donate any electrons but will take 1 electron.
