Answer to Question #316968 in General Chemistry for Nick

Question

I would like to know the volume of ammonium hydroxide required to add to an aqueous mixture of sulphuric acid and acetic acid to bring the pH up to 5

NH₄OH_(aq)+ CH₃COOH _(aq) = CH₃COONH_4(aq) + H₂O_(l)

2NH₄OH_(aq) + H₂SO_4(aq) -> 2(NH₄)⁺SO_4(aq)^2- + 2H₂O _(l)

Sulphuric acid molarity: 0.08 mol/L - 6597 mols total - 1.07 pH

Acetic acid molarity: 0.09 mol/L - 7176 mols total - 2.89 pH

Answer 1

Net Ionic: NH4OH(aq) → NH3(g) + H2O(l) *Note that ammonia hydroxide does not dissociate because it is a weak acid!
