Question
The pair (s) of compounds which can exist together in aqueous solutions is/are ?
Options
A.NaH2PO4 and Na2HPO4
B.NaHCO3 and NaOH.
C.Na2HPO3 and NaOH
D.NaHSO4 and NaOH.
Solution
(A) Both are acid salts ; so they can exist together in aqueous solution.
(B), (D) A base (NaOH) and an acid salt (NaHSO4 and NaHCO3) cannot exist together in solution.
Acid + base → salt + water.
(C) Na2HPO3 is a neutral salt ; so it does not further react with NaOH.
