Question

The species present in solution when CO 2 is dissolved in water are: (A) H 2 CO 3, CO 32- (B) HCO 3-, CO 32- (C) CO 2, H 2 CO 3 (D) CO 2, H 2 CO 3, HCO 3-, CO 32-

CO 2+ H 2 O leftharpoons H 2 CO 3 leftharpoons H ⊕+ HCO 3 ominus leftharpoons 2 H ++ CO 32- Hence, species present in solution are: CO 2 H 2 CO 3, HCO 3 ominus, CO 32-

Q. The species present in solution when $C O_{2}$ is dissolved in water are:

$H_{2} C O_{3}, C O_{3}^{2 -}$

$H C O_{3}^{-}, C O_{3}^{2 -}$

$C O_{2}, H_{2} C O_{3}$

$C O_{2}, H_{2} C O_{3}, H C O_{3}^{-}, C O_{3}^{2 -}$

$C O_{2} + H_{2} O ⇌ H_{2} C O_{3} ⇌ H^{\oplus} + H C O_{3}^{⊖} ⇌ 2 H^{+} + C O_{3}^{2 -}$

Hence, species present in solution are:

$C O_{2} H_{2} C O_{3}, H C O_{3}^{⊖}, C O_{3}^{2 -}$
