Ion Measurement (F-53,55)
There are two methods to measure the ion concentration using the ion electrode; one is the
calibration curve method and the other the standard addition method. The calibration curve
method is used to measure the ion concentration of an unidentified solution by preparing a
calibration curve which shows the relation between mV and concentration. The standard addi-
tion method is used to obtain the concentration of the target ions in the original sample by
changing only that concentration and then measuring changes in the difference in electric
potentials.
