Noah Stewart-Maddox Chem 121 10/12/11 Synthesis of Potassium Ferric Oxalate Trihydrate and The Determination of Oxalate Ion in Ferric Oxalate Trihydrate using Titrimetry Abstract: In this two-part lab‚ we will learn about coordination compounds and their uses with stoiciometry. We will also find out about how theoretical yield is calculated from a reaction we will create. We will also synthesize Potassium Ferric Oxalate Trihydrate (K_3 [〖Fe(C_2 O_4)〗_3]•3H_2 O) using a two step reaction. In

ketone with household bleach. The product is then isolated by steam distillation and is extracted into the distillate with ether. After the removal of ether‚ it leaves the product cyclohexanone. In experiment 6‚ cyclohexanone is oxidized by potassium permanganate. Manganese dioxide is filtered off and the filtrate is concentrated‚ acidified with hydrochloric acid and then cooled to yield crystalline adipic acid. OBJECTIVE: Experiment 4: To recover cyclohexanone from the oxidation of cyclohexanol

The solution we will be standardized by performing multiple calculations to ensure the upmost accuracy. The acid used for this titration will be KHP (C4H5KO4). Phenolphthalein we be added to the beaker of the dissolved acid before the titration will be added. The titration

The next test was the agar-water gel test. It was composed of a petri dish of agar-water gel with three wells. A drop of potassium permanganate‚ potassium dichromate‚ and methylene blue were introduced to the three wells simultaneously. The diameters of the three substances were measured after a regular 3 minute interval for 30 minutes. Results showed that potassium permanganate‚ which is the lightest‚ have the fastest diffusion rate while methylene blue‚ the heaviest‚ have the slowest diffusion rate

oxidation-reduction reaction between analyte and titrant (Harris‚2009). It involves the transfer of electrons between the two solutions. This experiment aims to determine the amount of iron or iron content of a razor blade by redox titration using potassium permanganate as a titrant and a self-indicating agent. Blank titration is used to estimate the titration error. Proper techniques and calculation regarding blank titration is also shown. This experiment will help the students to learn the proper conduction
