A package software for the colloid titration method was developed and examples of applications to actual experimental data are presented. Efficiency of software development was enormously improved by introducing a floppy disk unit as an external memory device instead of a cassette tape recorder used in Part. I. However, user's free RAM area was reduced to ca. 19 KB (B : Bytes) compared with the previous cassette-based system (ca. 27 KB). To cope with the decreased RAM area, the structured programming technique was adopted. That is, the whole programme consists of 9 small modules and each module is structured in itself in some cases. These 9 modules are chained to the main control module which is designed to be loaded automatically from the floppy disk file into the microcomputer only by switching on the system. Installation of a hard copy ROM made possible the output of screen images on printer. This system was found to facilitate the data processing by visual judgement of the results and improved to a greater extent the total throughput of the data processing.
Problems associated with applications of the colloid titration technique to wet end chemistry is described in detail.
