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 AgNO, (a). The student combines 10,00 ml of AgNO, (aq) with excess NasO.(69) and observe the formation of a white precipitato. The formation of pie precipitate is represented by the following equation. 2 AgNO, (om) + Na 80.00) Ag,SO.)+2 NaNO,(aq) (a) Write the balanced net ionic equation for the precipitation reaction 81 XX, c 0/10000 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 Mass of dry filter paper Mass of filter paper and precipitate immediately after filtration Mass of filter paper and precipitate after 10 minutes Mass of filter paper and precipitate after 20 minutes Mass of filter paper and precipitate after 30 minutes 0.888 4.828 4.37 4.01 3.796 (b) Use the data above to calculate the number of moles of Ag,SO.() (molar mats 311.8 g/mol) that precipitated (b) Use the data above to calculate the number of moles of Ag, S04() (molar mass 311.8 g/mol) that precipitated B / V X X $ ea HE 0/10000 Word Limit (c) Calculate the concentration of Ag" (ag) in the original 10.00 ml solution of AgNO, (e) B 7 IEE 0/10000 Word Limit (d) The concentration of AB (aq) determined by the student is significantly higher than the actual concentration of Ag (o) Based on the student's datatable identity an error in the experimental procedure that led to this result B 7 XX 5 EEN 0/10000 Word Lint (d) The concentration of A (a) determined by the student is significantly higher than the actual concentration of As" (ag). Based on the student's datatable, identify an ear in the experimental procedure that led to this result B 1 x x DIE 0/10000 Word Limit
