A testing time in store for Chemistry students on the 464 -written by Roger Walton
Many examination syllabuses for Chemistry at aged 16+ require students to be able to identify simple salts when given the results of tests on them. This requires quite a lot of practice if the student is to be confident in interpreting the results of such tests. The aim of this program is to allow you to do this on an Amstrad CPC 464 computer. The program is an adaptation of similar programs seen on other machines but it takes advantage of the Amstrad's window commands to produce a clear and attractive screen display.
The user is asked to choose which one of 40 salts to try to identify. He is then given a short description of the salt and invited to choose a test. The tests used axe fairly standard except that the Devarda's Alloy teat for nitrate ion has been chosen in preference to the older "brown-ring" test.
The student may choose to guess the identity of the salt at any time. Alternatively, if the student types Stop the identity of the salt is revealed and the student may choose another chemical. Help with the interpretation of the tests is given by typing Help.
