Question

3
Write the conjugate acids for the following Bronsted bases?
NH3, CH3COO, NH, HPO , H2O​

Answer 1

Answer:

1. NH₃ is a base so, it can accept a proton(H⁺) and form conjugate acid.  e.g., NH₃(base)  + H⁺  ⇔ NH₄⁺ (conjugate acid)
2. Acid-bases occur as conjugate acid-base pairs. CH3COOH and CH3COO- are a pair. H2O and H3O+ are a pair. The conjugate base of an acid is the base that is formed when the acid has donated a hydrogen ion.
3. O2–(aq) + H2O(l) → OH–(aq) + OH–(aq). OH– is the conjugate acid of the base O2–. OH– is also the conjugate base of the acid H2O.
