I have a free response question due for an Ap Chemistry class. It states, an experiment is to be performed to determine the mass percent of silver in a sample of the alloy, sterling silver. The equipment shown above is available for the experiment. A drying oven is also available. The equipment is (Beaker, Side arm flask, Buchner Funnel, Distilled Water, Graduated Cylinder, NaCl, 8M HNO3, Stir rod, Analytical Balance, Ring Stand, and a Ring). The questions they asked are, a) Briefly list the steps necessary to carry out this experiment, b) What measurements need to be collected to calculate the mass percent of silver in the sterling silver sample? c) List the calculations necessary to determine the mass percent of silver in the sterling silver sample, and d) Would NaBr be an acceptable substitute for the NaCl provided for this experiment? Explain. Any help would be greatly appreciated!
