Iron Determination Lab Report

Iron determination From accurately carrying out the iron determination experiment, this meant that we could then do some calculations to work out the exact concentration of iron in the tablet and the exact amount which is made up of iron, these are stated in my conclusion. We carried out this practical safely when rinsing and using the glassware as there was no breakages or injuries caused by the glassware. Whilst handling the chemicals we wore disposable gloves, goggles and lab coats at all times no not to expose ourselves to danger. We also disposed of the chemicals in the correct way. Whilst carrying out the iron determination experiment we found that the exact point that the liquid in the conical flask changed was unclear, we found it difficult to add the potassium manganite from the burette into the flask very difficult. If our results were …show more content…
The way we could tell this was from the example results which were gained from testing pure sugars, non-reducing sugars, starch and protein. The exact amount of sugars, non-reducing sugars, starch and protein is not readable so we can never get an exact reading, only whether they are or are not there. The food which we tested also did not represent every type of those foods, however the change in the amounts within them would be minimal. We could work even more accurately with the amounts of foods and substances which we added and record this. We could then work out a percentage for how much non-reducing sugar, sugar, starch or protein is present. I think that this was a good experiment because again we gained clear results. The results we found were conclusive to what we were aiming to find out. However the amounts of sugars, non-reducing sugars, starch and protein were unclear in the results, but this was not what we were aiming to find from the
