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. Add / Edited: 26.12.2014 / Evaluation of information: 5.0 out of 5 / number of votes: 1. However, as it is a salt of a strong acid and weak base it will have a pH in water of <7. NH 4 Cl NH 4 Cl is formed with a weak base, ammonium hydroxide (NH 4 OH), and a strong acid, hydrochloric acid (HCl). LIGHT DIAGNOSTICS CMV pp65 NH4Cl Leukocyte Separation Kit, alternate to #3246. chemistry. i might say that the pH might cut back. Therefore, when the salt is completely dissociated in an aqueous solution, it forms NH4+ and Cl- ions. Please register to post comments.
