H2CO3 (aq) + H2O (l) → H3O + (aq) + HCO3 - (aq)

Acid Base Conj. base Conj. acid

NH3 (aq) + H2O (l) → NH4 + (aq) + OH - (aq)

Base Acid Conj. acid Conj. base

Explanation:

Brønsted-Lowry's theory:

Acid → Donates H⁺

Base → Acceptes H⁺

H2CO3 (aq) + H2O (l) → H3O + (aq) + HCO3 - (aq)

Acid Base Conj. base Conj. acid

NH3 (aq) + H2O (l) → NH4 + (aq) + OH - (aq)

Base Acid Conj. acid Conj. base
