Abstract: According to the present invention, there is provided a method of producing a salt, including reacting M+X− with YH to generate XH and M+Y− and subsequently removing the generated XH to obtain the M+Y−.
In the method of producing a salt, M+X− is a salt of a cation represented by M+ and an anion represented by X−, M+Y− is a salt of the cation represented by M+ and an anion represented by Y−, XH is a conjugate acid of X−, YH is a conjugate acid of Y−, M+Y− is a compound that generates an acid upon irradiation with an active ray or a radioactive ray, a pKa of XH is larger than a pKa of YH, and a ClogP value of XH is larger than 2.
