Abstract The separation of a Fe3+ and Ni2+ mixture was firstly investigated; followed by the determination of the Fe3+ and Ni2+ content (concentration) in the original mixture. It was found that iron was a yellow solution and nickel respectively had a greenish colour. Their original concentrations respectively were 0.03669 M for iron and 0.03159 M for nickel. Introduction Ion exchange materials are insoluble substances containing loosely held ions which are to be exchanged with other ions in

Experiment 1: TLC Analysis of Analgesic Drugs 1/23/2011 Purpose: The goal of this experiment is to test our knowledge and understanding of TLC analysis by having us do a TLC analysis of analgesics to figure out their main chemical components. Calculations: 1.) Rf = Distance spot traveled/ distance solvent traveled Results: Table 1: TLC Analysis Analgesic Drugs | Rf Value | Acetaminophen | 0.323 | Aspirin | 0.597 | Caffeine | 0.081 | Unknown 154 (Plate 1) | 0.081‚ 0.306‚ 0.597

Using colorimetry to find the order of a reaction introduction Coloured solutions absorb some of the wavelengths in the visible region of the electromagnetic spectrum. A colorimeter can be used to measure the amount of light absorbed by a solution (the absorbance) and this is proportional to the concentration of the coloured species present. In this experiment you will use a colorimeter to investigate the reaction between bromine and methanoic acid:- Br2 (aq) + HCOOH (aq) ↓ 2Br-
