<Ammonia> is $\mathrm{NH_3}$, a pyramidal <molecule> with a <nitrogen> lone pair. The lone pair can accept a <proton> to form <ammonium> or coordinate a Lewis acid.

In <water>, the <Ammonia>-ammonium equilibrium affects <pH>. Molecular <Ammonia> and the ammonium ion therefore have different charge states and should not be treated as interchangeable species.https://webbook.nist.gov/cgi/cbook.cgi?ID=C7664417&Units=SI[NIST Chemistry WebBook: ammonia, formula and molecular identity]{ref}
