Question

Which of the followi9ng pair of acid redicals can be distinguished by using dil `H_(2)SO_(4)`?
A. `C_(2)O_(4)^(2-)` and `NO_(3)^(Θ)`
B. `NO_(3)O_(4)^(Θ)` and `NO_(2)^(Θ)`
C. `CI^(Θ)` and `Br^(Θ)`
D. `HCO_(3)^(Θ)` and `CO_(3)^(2-)`

Answer 1

Correct Answer - b

Hence ,distincition is possible
c. Both `CI^(Theta)`and `Br^(Theta)` have no reaction with dil `H_(2)SO_(4)`
d.Both `HCO_(3)^(Theta)` and `CO_(3)^(2-)` produce `CO_(2) uarr` which evolved with effecrescences
