Autoprotolysis occurs to a much smaller extent in ammonia (K_m = 1 * 10 -33 at -35^$\omicron$C) than in water.This means that A) very strong bases that would be protonated in water survive in their anionic form in ammonia. B) [NH₄⁺(am)] $\neq$[NH₂ - (am)]. C) strongly ionic compounds are very soluble in ammonia. D) ammonia is not very soluble in water. E) ammonia is not a very good solvent for a wide range of compounds.

Question

Quizplus · Accepted Answer

Autoprotolysis in ammonia is weaker than in water, meaning that ammonia is a weaker acid and weaker base than water. Therefore, very strong bases that would be easily protonated in water (such as anionic compounds) are more likely to survive in their anionic form in ammonia. This is reflected in choice A. Choices B, C, D, and E are either unrelated or incorrect statements.
