有一條al chem咁問
write all the bronsted acid in aqueous NH3
如果我答:
H2O , NH4+ , H3O+
但係marking冇H3O+
點解?
al CHEM:bronsted acid in NH3

be awared that this is an alkaline solution. H3O+ normally exist in acidic solution onlyIn ammounia solution, only the following rx is concerned,
NH3 + H2O <=> NH4+ + OH-
Among the 4 particles, H2O and NH4+ can donate the H+ ions and therefore are the Bronsted-Lowry acid.

then this question is very tricky.
it mentions "All". even in alkaline medium, NH4(+) should still be present as a result of equilibrium.
in CE levels, we wouldn't think about amminium ion;
in A-level, supposingly we're supposed to also think about ammonium, right?
