A salt consisting of a small, highly charged metal cation and the anion of a strong acid yields a(n) _____ solution. Since ammonia is a weak base, Kb is measurable and Ka > 0 (ammonium ion is a weak acid). Answer: calcium carbonate is a salt, it is neither acid nor base. Yeah. H 2 SO 3 also has protons it is able to donate, thus making it an acid. The solution containing a salt of strong acid and weak base is acidic. NH4I, ammonium iodide, is not an acid or base; it is only a salt. An acid-base reaction can therefore be viewed as a proton- process. I- is the anion of the strong acid, HI.
