B.
Its colourless and odourless nature
C.
Its low solubility in water
D.
Its high compressibility
Answer :
Its low solubility in water
Solution :
Its low solubility in water makes it of biological and geo-chemical importance. It forms carbonic acid with water which dissociates to give $$HCO_3^ - $$ ions. $${H_2}C{O_3}/HCO_3^ - $$ buffer system helps to maintain $$pH$$ of blood between 7.26 - 7.42.
