ion; it is added in excess to the oxidizing agent being determined. This would result to the formation of iodine which would be titrated with the standard thiosulfate solution. (2) For example in this experiement‚ the analyte that was used was copper in the form of CuSO4•H2O. It was strong enough to oxidize iodide ions to Iodine. The analyte was needed to be isolated‚ and we did this by precipitating it out of the solution. To precipitate out Cu (II) ions‚ NH3 was added dropwise – this is

EXPERIMENT 8 QUANTITATIVE DETERMINATION IODOMETRIC TITRATION OF COPPER CONCENTRATION IN AQUEOUS SOLUTION B Y RESULTS AND DISCUSSION Considered as moderately weak oxidizing agent‚ Iodine was used for the determination of strong reductants. Standard iodine solutions were found to have smaller electrode potentials as compared with the other oxidants‚ gaining them the advantage of imparting a degree of selectivity essential in the determination of strong reducing agents amid the presence

happen when you put zinc in copper II sulfate? • What will happen when you put copper in copper II sulfate? Predictions: • We can predict that zinc will react with the aqueous solution of copper II sulfate and we will notice a reaction. We can also predict that the copper will not react with the solution of copper II sulfate and no reaction will be noticed. Hypothesis: • It is hypothesized the zinc metal will have a precipitation reaction with the solution of copper II sulfate‚ because zinc is more

Introduction When iron is mixed to Copper (Ⅱ) Chloride; the product will be copper and iron chloride. However‚ in this experiment‚ we do not have the information of the oxidation number for iron nails. There are 2 different oxidation numbers for iron; that are 2 or 3. We will need to check each of the equations to find out the moles of each element in the equation. Then we can compare the ratio between the mole and the mass of iron and copper; that will be measured during the experiment. Finally

Note: I couldn’t paste in pictures and diagrams so please excuse any large spaces. Planing my investigation Method 1.Firstly I will measure 20ml of Copper Sulphate solution (CuSO4) in a measuring cylinder‚ for precise accuracy‚ and then pour the solution into test tube. I will place the test tube into a beaker and insulate the test tube‚ for minimum heat loss. (As shown in the diagram above.) 2.Secondly I will measure the required amount of Zinc (Zn) on a weighing scale‚ again for precise accuracy
