This piece of work is to help with the P7, M5 and D4 Unit 27 Applied Science 2010 - My teacher has signed this assignment off which means that it does meet the grading criteria. Hope it helps, all the best.
Please take note that this document cannot be copied and I would appreciate if you respect...
P7 – Carry out selected simple investiatons involvini transiton metal ions in aqueous solutonn
M5 – Explain selected reactons of transiton metal ions in solutonn
D4 – Use accurate chemical equatons in explainini reactons involvini transiton metal ions in
solutonn
Practcally investiate a ranie of reactons involvini solutons of transiton metal ionsn
Aimn to carry out investiatons involvini transiton metal ions in aqueous solutonn
Equipmentn
1n Beakers
2n Water
3n Ammonium soluton
4n NaOH soluton
5n HCl soluton
6n Measurini beakers
7n Variety of substances to react with the diferent solutons
8n Test tubes
9n Spatula (for solid substances)
10n Strrini rod
Risk Assessmentn
Make sure to wear ioiiles at all tmes to avoid the chemicals ietni into your eyesn This is
important as acids are very toxic and can cause irritaton if come into contact with, so avoid
spillaies, if however, some of the acid iets spilled clean up the arean Make sure to wash hands afer
the practcal has been carried outn Also, it is important to take care when workini with ilassware
because it can easily break and result with an injuryn If somethini does happen, make sure to seek
medical advice as soon as possiblen
Method:
1n Put a small amount of chromium into a test tuben
2n Use a measurini cylinder to measure 5ml-10ml of water and add it into the test tube with
chromiumn
3n Str the mixture in the test tube usini the strrini rodn
4n Observe the colour chanien
5n Record the observatonsn
6n Repeat steps 1-4 with other substances with water and also diferent solutonsn Use a
spatula for solid substancesn
