Q. Which property of $CO _{2}$ makes it biologically and geo-chemically important?

KCETKCET 2022The p-Block Elements

Solution:

Its low solubility in water makes it of biological and geo-chemical importance. It form carbonic acid with water which dissociates to give $HCO _{3}^{-}$ ions. $H _{2} CO _{3} / HCO _{3}^{-}$buffer system helps to maintain $pH$ of blood between $7.26-7.42$
