If the variable is linearly related to concentrations, such as the electrical conductance or the photometric absorbance, the term linear titration curve is used. When a logarithmic expression of the concentration or activity is used, such as the \\(\\rm{pH}\\), \\(\\mathrm{pM}\\), or the electrical potential in \\(\\mathrm{mV}\\), the curve is referred to as a logarithmic titration curve.","links":[{"term":"absorbance","url":"https:\/\/goldbook.iupac.org\/\/terms\/view\/A00028"},{"term":"conductance","url":"https:\/\/goldbook.iupac.org\/\/terms\/view\/C01243"},{"term":"titrant","url":"https:\/\/goldbook.iupac.org\/\/terms\/view\/T06386"},{"term":"titration","url":"https:\/\/goldbook.iupac.org\/\/terms\/view\/T06387"},{"term":"variable","url":"https:\/\/goldbook.iupac.org\/\/terms\/view\/V06600"}],"sources":["Orange Book, 2nd ed., p. 49 (https:\/\/media.iupac.org\/publications\/analytical_compendium\/)"]}],"altoutputs":{"html":"https:\/\/goldbook.iupac.org\/terms\/view\/T06388\/html","xml":"https:\/\/goldbook.iupac.org\/terms\/view\/T06388\/xml","plain":"https:\/\/goldbook.iupac.org\/terms\/view\/T06388\/plain"},"citation":"Citation: 'titration curve' in IUPAC Compendium of Chemical Terminology, 5th ed.
