What substance is acting as the Brønsted-Lowry base in the forward reaction below?
H2O + NH3 yields NH4+ + OH-
1 answer
NH3. A Bronsted-Lowry base accepts a proton. NH3 has a lone pair of electrons on the N, a proton (which needs two electrons) sits down there to produce the NH4^+. So NH3 is the base and NH4^+ is the conjugate acid.
