Introduction

Flame test AIM Carry out test on different compounds and write down what it looks like. APPARATUS Watch glass Bunsen burner Nicronwire with a small loop at the end Cleaning paper CHEMICALS USED:- Hydrochloric acid, which is (crossive) Calcium acetate Lithium sulphate Sodium chlorate Potassium chloride Copper oxide RISK ASSESMENT Wear safety goggles when carrying the flame test and appropriate clothing. Take small quantity hydrochloric acid. When busen burner is not being used, close the air hole so that you can see the yellow flame. Keep your clothing away from the flame. Calcium acetate Irritant to eyes. Avoid raising and it also irritant to eyes. Keep it away from water it could cause water to boil if because of the salt. ...read more.

Harmful if inhaled or swallowed. Solution labelled if stronger then 2m .it may cause your eyes and skin to irritate. These substances are dangerous with material like sugar, wood, clothes and etc.these solution ignite easily burn vigorously when dry. This should not be made available in the lab with concentrated sulphur. Copper oxide Harmful if swallowed. Dust irritates lungs and which could cause a health risk. It is dangerous with aluminium, magnesium. Explosives mixers are formed. Do not react copper oxide with aluminium in thermite reactions. Important = If you spill any chemicals on your skin and eyes quickly wash it for it for 10 min and if you can still feel it keep it like that until you don't feel anything. ...read more.

Conclusion

Tap the loop against the dry part of the watch glass to remove the acid. * Hold the loop in the edge of the flame. * Then record the colour of the flame in the table. Then I choose from the following colours: -brick red (orange red), green (with blue streaks); lilac (pale purple); yellow. RESULTS TABLE METAL CATION COLOUR OF FLAME SODIUM Na+ YELLOW POTASSIUM K+ LILAC CALCIUM CA 2+ ORANGE COPPER CU2+ GREEN LITHIUM LI+ RED CONCLUSION I found the colour of different metal when I flame tested each of them. I found that when you burn sodium you get a yellow colour, when you burn potassium you get a lilac colour. This also shows us that cat ion is positively charged. This will also help me identify the chemical colours when they are burning. ?? ?? ?? ?? ATIF ESHAQUE KAMAL 1 ...read more.
