NH3

[Ami_Pant_4G]

If a molecule has NH3 is it safe to assume it is a base?

[Chris Tai 1B]

NH3 is more complicated since it can act as both an acid and a base, just like water. If it donates a proton, it becomes NH2-, and if it accepts a proton, it becomes NH4+. So, NH3 is technically amphiprotic, meaning it's hard to determine if it'll always be a base (it depends on the solution it's in).

NH3 can be both an acid or a base so its amphiprotic and will depend on the situation.

[Snigdha Uppu 1G]

NH3 is a molecule that is amphoteric so it can act as a base or acid. Therefore, you can not assume anything.

[Natalie C 1K]

you cannot assume it is a base because it is amphiprotic (it can act as an acid or a base)

[Mallika Chimpiri 3K]

NH3 is amphiprotic, meaning it can act as a base or an acid, so you have to look at the reaction!
