Suppose that 0.323 g of an unknown sulfate salt is dissolved in 50 ml of water. the solution is acidified with 6m hcl, heated, and an excess of aqueous bacl2 is slowly added to the mixture resulting in the formation of a white precipitate.
1. assuming that 0.433 g of precipitate is recovered calculate the percent by mass of so4 (2-) in the unknown salt.
2. if it is assumed that the salt is an alkali sulfate determine the identity of the alkali cation.
