This results to the formation of water H-O-H and sodium nitrite. Because most acids are weak acids, the best guess would be that HCOOH is a weak acid (weak electrolyte). The word conjugation means linking with other species. 1A) What is the conjugate acid and base of C6H5NH2? The key difference between acid and base is that acids have pH values ranging from 1 to 7 whereas bases have pH values ranging from 7 to 14. pH value is the minus logarithm of H+ ion concentration. The strength of the acid decreases going down the column, while the strength of the conjugate base increases. Complete step-by-step answer: According to Bronsted Lowry theory, acids are good proton donor then after donating a proton they will form conjugate base while on the other hand we have bases which are good proton acceptor thus after accepting one proton they will form conjugate acid. Ammonium will most likely to donate its proton to hydrogen sulfide ion. All other acids are weak acids and ionize to a much lesser amount.
