The specties present in slution when ` CO-2` is dissolved in water are :

A

` H_2CO_3, CO_3^(2-)`

B

`HCO_3^(o+),CO_3^(2-)`

C

`CO_2 H_2CO_3`

D

`CO_2 H_2 CO_3 HCO_3^(o+) CO_3^(2-)`

Text Solution

Verified by Experts

The correct Answer is:
D
`CO_2 +H_2O hArr H_2 CO_3 hArr H^(o+) + HCO_3^(o+) hArr H^(o+) +CO_3^(2-)`
Hence , species present in solution are `CO_2, H_2 CO_3`
`HCO_3^(Θ), CO_3^(2-)`.
