Chemically, explain your answer. Adding HCl will shift the equilibrium to the right, but will neutralize OH- and simply make the solution acidic, and make phenolphthalein colorless. When solid NH4Cl is dissolved in water, you have an acidic solution because NH4^+ is a proton donor. 2 1. 0.35 M ammonium chloride is a highly soluble salt compound in water, that will fully dissociate into 0.35 M of ammonium cation and 0.35 M of chloride anion: Ka = [NH3][H3)^+]/[NH4^+] Assume you have a solution that contains 0.100 M NH4Cl. Calculate the amount in moles of NaCl formed. C) a strong acid. What is the pH of the neutralized solution? As mentioned in the other answer, NH4Cl is an "acidic" salt, formed by the neutralization of a strong acid (HCl) with a weak base (NH3). Is it on the OH- to produce more of H2O or is it on the NH3 to produce more of the NH4+. As per the literature NH4Cl when dissolved in water, its pH needs to be increased beyond 8.5 and preferably 10.5 (by addition of CaO) so that NH4+ is converted to NH3 and evolution occurs.
