Compar the acidic nature :
(a) `H_2O` and `H_2O_2` and (b) Co and `CO_2`

Text Solution

Verified by Experts

`H_2O` is neutral . `H_2O_2` is weakly acidic. `H_2O_2` forms sats upon neutralisation with alkali.
`H_2O_2 + NaOH rarr NaHO_2 + H_2O`
`H_2O_2 + 2NaOH rarr Na_2O_2 + 2H_2O`
(b) Co is neutral while `CO_2` is acidic
