1.	NH3 is Lewis base as well as bronsted base why give reason for
Answer» is both a BRONSTED and a Lewis BASE, owing to the unshared electron pair on the nitrogen. The bisulfite ion is amphiprotic and can act as an electron donor or acceptor. Note. All Bronsted–Lowry bases (PROTON acceptors), such as OH−, H2O, and NH3, are also electron-pair donors.
