In the practical, a sample of mummion in the form of dried mud from a lake was provided. The objective was to purify the sample and extract mummion salt by separating it from the insoluble impurities.
The context is presented in the given text.
Mummion was a common substance used in ancient Egypt to preserve the bodies of 'mummies'. Along with other natural preservatives, it was used to treat the organs before wrapping the bodies. This purification process is still practiced today and includes extracting salt from sea water for everyday use.
The method used for the study.
Safety measures, such as the use of lab coats and safety goggles, were implemented to ensure safety during the procedure. The first step involved transferring around 4g of dried mum
...mion mud into a beaker using a spatula. Next, 75ml of distilled water was added to the same beaker. The mummion mud was then dissolved in the distilled water by stirring, while keeping the sand and iron (III) oxide separate. Subsequently, we filtered the mixture by placing folded fluted filter paper inside a funnel and placing the mud on top of it. Finally, we positioned the funnel on a conical flask.
The mud will eventually separate into liquid form, which is then moved to an evaporation dish. Position the evaporation dish on top of a tripod over a lit Bunsen burner with a blue flame. After some time, turn off the Bunsen burner, leaving around 15ml of liquid. Leave the mixture undisturbed until white crystals appear in the dish. The equipment used in this process includes:
The text discusses the findings and fina
statements.
After filtering the substance, it produced a clear liquid. However, some of the other groups that performed the same experiment had a slightly pink liquid after filtering the mud, which could indicate slight contamination.
Analysis
Using fluted filter paper increases the filter area, resulting in slightly more effective and quicker filtering.
