A 30.00-mL solution of HBr was treated with 5 mL of freshlyboiled and cooled 8 M HNO3, and then with 50.00 mL of 0.3650 MAgNO3 with virgorous stirring. Then 1 mL of saturated ferric alumwas added and the solution was titrated with .2870 M KSCN. When3.60 mL had been added, the solution turned red. What was theconcentration of HBr in the origninal solution? How manymillimgrams of Br- were in the original solution?
