Example of amphoteric salts NaHS, NaHCO3,
Na2HPO4, NaH2PO4
Both reaction will support each other extent of hydrolysis and extent of dissociation is same.
Both reaction will support each other extent of hydrolysis and extent of dissociation is same.
ILLUSTRATIVE EXAMPLE: Calculate pH of solution of
(1) 100 ml 0.1M H3PO4
+ 100 ml 0.1M NaOH.
(2) 100 ml 0.1M H3PO4
+ 200 ml 0.1M NaOH.
(3) 100 ml 0.1M H3PO4
+ 300 ml 0.1M NaOH.
(4) 100 ml 0.1M H3PO4
+ 400 ml 0.1M NaOH.
@@@
Pls elaborate how NaHs is an amphoteric salt.
