AUTOMATION OF POTENTIOMETRIC TITRATION WITH A PERSONAL COMPUTER USING AN IBM COMPATIBLE INTERFACE SYSTEM

Abstract

An IBM compatible interface card system with infrared source-detector data sampling was designed and tested for automation of potentiometric titrations with personal computers without continuous measurement of the volume of the titrant. The device with other appropriate apparatus and setup was tested for determination of iron(II) samples with potassium dichromate. The automation method developed was tested to the titration of 1.500 x 10-4 M iron(II) sample and gives a reliable result of 1.496 x 10-4 M iron(II) with a relative error of 1.76%.
