Point 1 marks the pH at the beginning of the … WebThe buffer range is the pH range over which a buffer acts effectively. ... The more similar the concentration of the two components, the greater the buffer capacity. At a titration curve, buffer capacity will be at its maximum when pH = pKa, which occurs at the half-equivalence point. References. Theodore Lawrence Brown, et al. Chemistry : The ... WebKey features of titration curves: Equivalents: the x-axis scale for titrations is given in moles of base/moles of acid. Therefore, it varies from 0 to 1 for an acid that releases one proton (monoprotic), from 0 to 2 for a diprotic acid, 0 to 3 for a triprotic acid. ...
