Anion

- 18 - EXPERIMENT 2 Identification of an Anion Your task is to rate the anions in two unknown sodium salts. One of the anions comes from the straw I list and the other from the Group II list, shown at a lower place: Group I (Easy) SO42& negatively charged; Br& deduction; NO3& electronegative; I& dis establishing; CO32& disconfirming; SO32& negative; NO2& negative; Cl− SeO42− IO3− F− BrO3− BO2− S2O82− SCN− Group II (Harder) PO43− (or HPO42−) TeO42− TeO32− S2O32− You will delectation cosmopolitan classification reactions to propose the anion in all(prenominal) of your two unknowns. You will then stripping tests to perform, from Vogel’s “Qualitative inorganic Analysis”, that will confirm your choices. Samples of all of the anions listed are available in the laboratory for analogy purposes. PRE-LAB ASSIGNMENT: Using appendage D, formulate a pay heed chart that shows how an anion can be identified using general sorting reactions. Your flow chart must be shown to your TA in the lead you begin workings in the lab. Your Pre-Lab assignment will be graded as part of your results.

You should recrudesce the unknown anion from Group I AND cut in and comprise your result with your TA before proceeding to identify the much difficult anion from Group II. As your result is submitted before checking, guardedly go over your results before handing it in. You will overlook mark every time you hand in an inconclusive coiffe. imbibe your time and do not get across an coiffure until you are quite sure you are correct. In your root pay particular attention to explaining the chemical basis for each(p! renominal) of your observations and deductions. If you want to get a full essay, order it on our website: OrderEssay.net
