Write the chemical reaction that is responsible for the ph of a buffer which contains nh3 and nh4cl. write the reaction in such a way that is appropriate for a ka.
Ammonia (NH₃) shows basic character in aqueous solution: NH₃ + H₂O ⇄ NH₄⁺ + OH⁻. This is basic buffer, because contains hydroxide anions. Ammonium chloride is salt and in water dissociate: NH₄Cl → NH₄⁺ + Cl⁻. Ammonium ion shows acidic character in aqueous solution:: NH₄⁺ + H₂O ⇄ NH₃ + H₃O⁺. Ka = [NH₃] · [H₃O⁺] ÷ [NH₄⁺].
