WebSep 6, 2024 · I did some research online but I still couldn't get any conclusion. Some 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 $\ce{H+}$ ion from the ionization of the weak acid … WebThe buffer solution will have a higher capacity if it is highly concentrated. It is normally determined using a technique called titration. Buffer capacity is denoted with ‘β’. Formula. The formula that is used to measure the buffer capacity of a buffer or solution in chemistry is as follows: β = ∆A or ∆B∆pH. In the given formula:
