This ebook was once digitized and reprinted from the collections of the college of California Libraries. It was once made from electronic photographs created throughout the libraries’ mass digitization efforts. The electronic pictures have been wiped clean and ready for printing via automatic tactics. regardless of the cleansing procedure, occasional flaws should be current that have been a part of the unique paintings itself, or brought in the course of digitization.

Cl– + H2O o no reaction NH4+(aq) + H2O(l) mo NH3(aq) + H3O+(aq) The resulting hydronium ion (H3O+) shows that the ammonium chloride solution is acidic. It shows acidic properties. It turns litmus paper red (Figure 16). Figure 16 Ammonium chloride (NH4Cl) solution is acidic. The Properties of Solutions 31 In summary, * The salts of strong bases and strong acids (for example, NaCl) do not hydrolyze. Their solutions are neutral. * The salts of weak bases and strong acids (for example, NH4Cl) hydrolyze.
