A conjugate acid-base pair differ by a single hydrogen ion. Carl.sde ; 2d;q h7;uwuyjv ;tsb (muj5;pbonic acid and carbonate (choice A) differ by two hydrogen ions so are not a conjugate acid-base pair. Boric acid and its hydroxide adduct (choice B) differ by a hydroxide ion and ammonia and hydroxylamine (choice D) by an oxygen atom.
This question is categorised au;7(u ju t d;jbew;ml; p;sh2yd qv.s5s very hard as the student must recall the definition of a conjugate acid-base pair, interpret the structural formulas of unfamiliar molecules and identify a conjugate acid and base without the aid of a reaction equation.
