What is Mummion likely to contain?
In the inference, if the result was positive, it means the chemical was present in the Mummion.
In this investigation the thing I feel was most successful was how i accurately purified the Mummion. By not only using one filter paper at a time, I used two. This allowed the solution to go through two stages of paper, allowing it to be filtered well. This allowed our Mummion crystals to become more pure.
In this investigation I feel I could have improved on the amount of crystals we came out with. This was mainly because the evaporating dishes were split. This meant that we had to re-do the whole purification of the Mummion again. This wasted a lot of time, which could have been spending completing the qualitative tests.
I think I did keep to the plan throughout this investigation. Although when purifying the Mummion, we did use more chemical to get a clearer result. For example, we added more distilled water to try a spate the chemicals more.
By completing this experiment successfully, it allowed me to find out that Mummion contained sodium, chloride and carbonate ions.
