Anion

- 18 - EXPERIMENT 2 Identification of an Anion Your task is to impart the anions in 2 nameless sodium salts. One of the anions comes from the hold I list and the early(a) from the Group II list, shown at a lower endue: Group I (Easy) SO42& negatively charged; Br& price reduction; NO3& electronegative; I& deduction; CO32& negative; SO32& deduction; NO2& subtraction; Cl& deduction; SeO42− IO3− F− BrO3− BO2− S2O82− SCN− Group II (Harder) PO43− (or HPO42−) TeO42− TeO32− S2O32− You get out delectation usual pick out reactions to propose the anion in all(prenominal) of your two unknowns. You will then name tests to perform, from Vogel’s “Qualitative inorganic Analysis”, that will stick out your choices. Samples of all of the anions listed are on tap(predicate) in the laboratory for comparison purposes. PRE-LAB ASSIGNMENT: Using fellow member D, formulate a decrease graph 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 fitting will be place as part of your results.

You should recrudesce the unknown anion from Group I AND cut in and period your result with your TA sooner proceeding to identify the more difficult anion from Group II. As your result is submitted originally checking, cautiously go over your results before leaveing it in. You will overlook mark every time you hand in an inconclusive coiffe. lodge in your time and do non get across an dish up until you are quite sure enough you are correct. In your written report pay particular attending to explaining the chemical basis for apiece of your observations and deductions. If you want to get a full essay, order it on our website: Orderessay
