Pure water will auto-ionize to produce a hydronium ion and a hydroxide ion: 2H2O --> H3O+ + OH- comapare the componets within the final reaction mixture. It would contain A) More water molecules because water is turner acid and base than H3O+ and OH- B) More water molecules because water is a weaker acid and use than H3O+ and OH- C) More H3O+ and OH- because the ions are stronger acid and bases than water molecules D) More H3O+ and...
