本题详细解析:
A conjugate acid-base pair dif4shaajb 1*j3 )5hpsrv6ws dd8fer by a single hydrogen ion. Carbonic 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 as very hard as the student must recall the definition of a conjugate acid-base pa rssd1j 6aj3 hh)5psb4w*ad8v ir, interpret the structural formulas of unfamiliar molecules and identify a conjugate acid and base without the aid of a reaction equation.
