The pairs of compounds which cannot exist together in aqueous solution are

`NaHCO_(3)+NaOH`

`NaHCO_(3)+Na_(2)CO_(3)`

`Na_(2)CO_(3)+NaOH`

`NaOH+NaCI`

Text Solution

Verified by Experts

The correct Answer is:

`NaHCO_(3)` is a sodium salt of weak acid, while NaOH is a strong base, that is why they react and cannot exist together in solution.
`NaHCO_(3)+NaOH rarr Na_(2)CO_(3)+H_(2)O`
