1. Siver nitrate is sadded to a solution containing an unknown salt. An off-white colored precipitate forms. Nitric acid is added to the mixture, the precipitate dissolves and a gas is given off. What is the anion present: Cl-, Br-, I-, PO4 3-, SO4 2-, CO3 2- ?

2. A common table salt substitute gives a lavender flame test. It also yields a nitric acid insoluble white precipitate upon the addition of silver nitrate. What are the formula and name of this commpound sold as salt substitute? Why are these ions absent: Cl-, Br-, I-, PO4 3-, SO4 2-, CO3 2-?
