Use the information in the pictures if needed and solve for the unknown D. please type the answers because it is much easier for me to understand that way. Unknown D To the unknown mixture, 3 drops of 6 M HCl was added and no precipitate formed. To the liquid that was left, 3 drops of 0.10M (NH4)2SO4 was added and a precipitate formed. The precipitate was isolated by centrifuging and the liquid from the top decanted for further testing. To the decanted liquid, the solution was made basic and a few drops of (NH4)2C2O4 was added. No precipitate formed. The liquid was tested for Mg2+ and a bright blue jelly ppt formed. To the unknown, a separate NH4+ test was done and the litmus paper used to test the pH turned blue. To the unknown, a flame test was performed and the color emitted was a light purple-red. What ions are in the unknown?

(TOPIC: Gravimetry multi-component analysis) A 0.8612-g sample of a mixture of sodium bromide, sodium iodide, and sodium nitrate is analyzed by adding silver nitrate and precipitating a 1.0186-g mixture of silver bromide and silver iodide. The precipitate is then heated in a stream of chlorine gas, which converts it to 0.7125 g of silver chloride. Calculate the %w/w nitrate in the sample.
