Titration is a means of determining the properties of one chemical by observing the change brought about by the addition of another, known solution. Of course, this program is likely to be of interest to chemistry students.

I was a bit doubtful while loading the program. A cassette insert of flimsy paper with the title on it and a self adhesive label on the cassette itself, do not give a tremendous impression, but when it loaded, I was pleasantly surprised.

The instructions are very scant and I think this cassette is best used alongside a text book.

There are details of 10 indicators that you can use in the simulated titration and the whole thing is totally menu-driven. There is also a worksheet which gives you six questions or things to do using the program and claims that these are A-level questions. All I can say is that I must be brighter than even I thought I was!

A good tape and a good idea that could, and should, be taken much further.
