Cations i found out what cations where present by doing a flame test when i put my substance in the bunsen burner i got a bright yellow colour which means that the cation for my substance was sodium ions. Please speak up during sessions to test your ideas on your peers and share your own experience and views on the matters under discussion waste money or result in. I have been given this exciting task for my science project, it is about the unknown substance, known as the mummion, i need to find out its molecular structure, by doing many different tests, i have already done the flame test, with a result of a orange flame, this tells me what the ph is, i need to carry out another, two more practicals, both being the chemical tests, i am unsure on how this.

Firstly i done the flame test which gave me that cations that where present in this and then i done some specific test for to find anions after doing all of this i found my cations and anions that where present in the mummion sample that i was given. G623/02 test: all questions had been attempted suggesting that there was adequate time to answer the paper there was a feeling in the examining team that the quality of written work was lower this session compared to the january cohort. The results yielded from the test suggest that the mummy was 985 percent primate and 15 percent unknown - a similar genetic structure to that of a human being. The main purpose of this investigation is to test and analyse mummion by doing this we would hopefully be able to see what chemicals it contained extracts from this document. The results for a pure substance should show that: the substance produces just one spot on the plate the distance travelled by the substance is identical to a known sample of that substance on the.
After this, there should be a instant colour change annion test: results: flame test: flame test was carried out to define what cation was present in the mummion crystals the colour of flame that we got was of yellow/orange, by looking at this i could say that chloride was present in the mummion.

For example, a medical technician might test a urine sample to determine if glucose is present qualitative analysis is a structured set of methods used to determine the identities (but not the amounts) of the components that make up a mixture. Qualitative analysis is used to identify and separate cations and anions in a sample substance unlike quantitative analysis, which seeks to determine the quantity or amount of sample, qualitative analysis is a descriptive form of analysis in an educational setting, the concentrations of the ions.
