    I missed a couple of the Chem experiments during the year ... I have them written up, but I'm missing the results / calculations / data.

    In particular these:
    Determination of the concentration of ethanoic acid in vinegar.

    Determination of the amount of iron in an iron tablet.

    Determination of the percentage (w/v) of hypochlorite in bleach.

    An iodine/thiosulfate titration.

    A potassium manganate (VII) / Ammonium iron (II) sulfate titration.

    Determination of the amount of water of crystallisation in hydrated sodium carbonate.

    Estimation of total hardness using ethylenediaminetetraacetic acid

    Estimation of dissolved oxygen by redox titration.

    Determination of total suspended and dissolved solids (expressed as p.p.m.) by filtration and evaporation respectively. Determination of pH.

    Colorimetric experiment to estimate the concentration of free chlorine in swimming-pool water.

    If anyone has a full or nearly full set, and is willing to help, I would greatly appreciate if they let me know, and we can sort the details by PM.

    Thanks.

    Could you not get them of a classmate?

    No, no one had brought their experiment copy in, and the next day we had a day off.
    I need it by Tuesday.

    Why don't you just use your book and take figures from the calculation questions?

    Do you think that would be acceptable?

    I don't see how its any different to asking people here to supply numbers. The chance that your lab book is going to be inspected by an inspector is extremely unlikely anyway.
