Does temperature affect buffer capacity
WebThe buffer capacity is defined as the amount of acid or base you can add without changing the pH by more than 1 pH unit. I will define "significant change" as 1 pH unit. The equation is HCO₃⁻ + H₂O ⇌ H₃O⁺ + CO₃²⁻ * (1)* pH = pKₐ + log ( [CO₃²⁻]/ [HCO₃⁻]) = pKₐ + log (0.50/0.35) = pKₐ + 0.155 WebSome said that the buffering capacity decreases when temperature increases because of the increase in ionisation of the weak acid molecules and therefore, some of the conjugate base ion will be used to neutralised the H A + ion from the ionization of …
