All hydrohalic acids in Period 3 or below, Correctly order the steps necessary to solve weak-acid equilibria problems. So water, or H2O, can be written as HOH. An aqueous solution of ammonium nitrate will be: a. acidic b. basic c. neutral d. either acidic or basic depending on the concentration of the ammonium nitrate e. need more information to be determined, What is the pH of a 0.0100 M ammonium formate solution? NHCl, ammonium chloride, and I have to find out its' nature. C5H5NHClO4 The weak conjugate acid of the weak base pyridine is pyrridinium ion. Would a 0.1 M aqueous solution of ZnCl2 be acidic, basic, or neutral? This is the most wide-ranging of the three (i.e.
