摘要： An acidity measuring apparatus includes a measuring container for accommodating an electrolyte solution including one of a 1,2-benzoquinone derivative and a 1,4-benzoquinone derivative, an organic solvent, an electrolyte and an acid-containing subject for measurement; a working electrode, a counter electrode and a reference electrode section provided in the measuring container and immersed in the electrolyte solution; and a control section for sweeping a potential of the working electrode within a prescribed range and for detecting a value of a pre-peak current generated by the acid and flowing between the working electrode and the counter electrode.
