Ammonium

Postby victoriatanaka1C » Thu Jun 14, 2018 1:19 am

We know NH3 is a base, but assuming we didn't know this, how would we know that it would accept protons rather than lose them? Is it because it wants to form NH4, which is a strong acid?

And what are good acids/bases to have memorized? I didn't write down what Dr. Lavelle suggest we know...

As discussed many times a nitrogen atom with a lone pair acts as a base. The lone pair can pick up a proton.

Draw the Lewis structure for NH3 and you will see the N atom has a lone pair that can bond to H+ to form NH4+.
