Applied science mummion assignment Task 1 – purification Aim We were given a sample of mummion in the form of dried mud from a lake; the aim of the practical was to purify the sample and separate it from the insoluble impurities into the form of mummion salt. Context A long time ago mummion was used to preserve the bodies of ‘mummies’ in ancient Egypt‚ mummion along with other naturally occurring preservatives was used to treat the organs before the bodies were wrapped. This purification practical

sulphate and bromine. The Cation was sodium and the Anions where sulphur and bromine this means that my sample was sodium sulphate or sodium bromide. Evaluation My experiment went very well but if I could redo this I would make some changes. The Mummion that I had filtered was not completely clear‚ so I would filter this couple of times before putting it into an evaporating basin. There may have been some measuring errors whilst... Cations I found out what Cations where present by doing a flame

the heart and then they stored these organs in jars and filled the hole back up with linen and spices. After this‚ the body would then be left to dry by using a salt (natron) mixture called a mummion which absorbed all the moisture from the body to dry it out‚ and then it was wrapped up in linen bandages. Mummion is an inorganic solid that is obtained from dried up lake beds and it used to mummify the dead bodies. I am going to explain what Ions are including Cations and Anions because it is the background
