this covers spectrometer and the related practical . it up to distinction level

this is unit 19 A part 2 . it up to distinction level . it includes : Practical 2: determine the iron content of an iron tablet. Part 1: standardisation of potassium permanganate with sodium oxalate solution. Part 2: determine the concentration of iron by titrating potassium permanganate solution against an unknown conc of iron sulphate made from iron sulphate tablets and sulfuric acid.

this is unit 19 A part 1 . it is distinction level graded by my teacher . this will cover : Practical 1: determine the copper content in brass. Part 1: make the brass solution. Part 2: make a series dilution of copper nitrate and then ran all samples through the colorimeter.

this is part 5 of unit 19 B . it up to distinction level it covers Infrared Spectroscopy.

this cover unit 19B part 3 . it up to distinction level Section 3: Determine empirical and molecular formulae from percentage elemental composition data and mass spectra.

This document achieved a distinction grade, there was no feedback given apart from good work achieved. This document explains the steps taken in the first practical for unit 19 we did and is in the layout of a tutorial booklet as wanted.
