According to the chemists, ammonia is a weak acid.

According to the Wikipedia article, "One of the most characteristic properties
of ammonia is its basicity. Ammonia is considered to be a weak base."

It also says...

"Although ammonia is well known as a weak base, it can also act as an
//extremely// weak acid. It is a protic substance and is capable of formation
of amides (which contain the NH2ˆ’ ion)."

So it appears to depend on the reaction.
