Ammonium chloride
= Ammonium chloride
<Ammonium chloride> is the ionic salt $\mathrm{NH_4Cl}$. In <water>, its ammonium ion can donate a <proton>, so the solution's acid-base behaviour is related to the <Ammonia>-ammonium equilibrium.
This is an example of a salt whose dissolved ions affect <pH>. Calling a substance a salt describes its ionic composition; it does not imply that every aqueous solution of it must be neutral.
