Yоur tаsk is tо determine the fоrmulа of аn unknown solid. You are told that the unknown consists of a group II cation (Mg2+, Ca2+, Sr2+, or Ba2+) and a group 7 anion (Cl-1, Br-1, or I-1). You perform an experiment by reacting your unknown salt separately with solutions containing sulfate, carbonate, oxalate, and iodate. You are looking to see if your unknown makes insoluble precipitates. A summary of your data is below: SO4-2 CO3-2 C2O4-2 IO3-1 Unknown precipitate formed precipitate formed precipitate formed no precipitate Next you react your unknown salt with solutions of Cl2 in water, Br2 in water, and I2 in water with the addition of hexane. Upon shaking each solution you observe that the top later of each mixture is purple. What is your unknown?
