    Well it is listed as a mandatory experiment in both my text book and lab book so I assume it is.

    The experiments in the front of the papers are the experiments that have come up before, Those two experiments haven't been seen on exam papers apparently

    No they have never come up... and they never will. The understanding that go's into them is also applied in the other, more detailed experiments. They cant justify giving away 50 marks for something which is much easier than other aspects of the course.

    They come up a bit in pass I think.

    I wouldn't say that. They can always combine two or more experiments in one question if they can't justify giving them their own one. They did it with chromatography and steam distillation in 2008.

    As far as I know I think those two experiments are for pass and not on the honours. Because in my book they are in there but it says they are for pass only.

    Theres nothing that can be ask in those experiments that cant be asked in one of the more complicated titrations... they are mainly just there as an introduction to titration technique.

    Theres probably a 2% chance of them ever being directly asked. They are too easy. Happy days if they are asked, but for an honors paper they wont test the potential A1 student.
