The pair of compounds which cannot exist...

The pair of compounds which cannot exist together in aqueous solution is ,
(I)`NaH_(2)PO_(4) and NaHCO_(3)` (II)`Na_(2)CO_(3) and NaHCO_(3)` (III)`NaOH and NaH_(2)PO_(4)` (IV)`NaHCO_(3) and NaOH`

A

`NaHCO_(3) and NaOH`

B

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

C

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

D

`NaHCO_(3)` and `NaCI`

Text Solution

Verified by Experts

The correct Answer is:
a
`NaHCO_(3)` and `NaOH`cannot coexist in solution because `NaHCO_(3)` is an acid sqalt it reacts with the base `NaOH` as follows
`NaHCO_(3) + NaOH rarr Na_(2)CO_(3) +H_(2)O`
