Chapter 16.10, Problem 5Q
To measure the relative strengths of bases stronger than OH−, it is necessary to choose a solvent that is a weaker acid than water. One such solvent is liquid ammonia.
- (a) Write a chemical equation for the autoionization of ammonia.
- (b) What is the strongest acid and base that can exist in liquid ammonia?
- (c) Will a solution of HCI in liquid ammonia be a strong electrical conductor, a weak conductor, or a nonconductor?
- (d) Oxide ion (O2−) is a stronger base than the amide ion (NH2−). Write an equation for the reaction of O2− with NH3 in liquid ammonia. Will the equilibrium favor products or reactants?
