For parts of the free response question that require calculations, clearly show the method used and the steps involved in arriving at your answers. You must show your work to receive credit for your answer. Examples and equations may be included in your answers where appropriate. A student wishes to determine the concentration of Ag (aq) in a solution of AgNO3(aq). The student combines 10.00 mL of AgNO3(aq) with excess Na2SO4 (aq) and observes the formation of a white precipitate. The formation of the precipitate is represented by the following equation. 2 AgNO3(aq) + Na S04 (aq) Ag, SO4(s) +2 NaNO3(aq) (a) Write the balanced net ionic equation for the precipitation reaction. c EE B x x 2- 2 Ag (aq)+504 (aq) - Ag,SO4(s) 11/10000 Word Limit The student collects the precipitate by filtration and measures the mass of the filter paper and precipitate every 10 minutes as it dries. The student records the data in the following table. 0.88 g 4.82 g Mass of dry filter paper Mass of filter paper and precipitate immediately after filtration Mass of filter paper and precipitate after 10 minutes Mass f filter paper and precipitate after 20 minutes Mass of filter paper and precipitate after 30 minutes 4.37 g 4.01 g 3.79 g Mass of filter paper and precipitate after 30 minutes (b) Use the data above to calculate the number of moles of Ag, SO4(s) (molar mass 311.8 g/mol) that precipitated B 1 U x x $ C 0/10000 Word Limit (c) Calculate the concentration of Ag+ (aq) in the original 10.00 mL solution of AgNO3(aq). B 1 u x? X2 5 C 12 0/10000 Word Limit (d) The concentration of Ag+ (aq) determined by the student is significantly higher than the actual concentration of Ag+ (aq). Based on the student's data table, identify an error in the experimental procedure that led to this result. B 1 u x x $ C
