A solution containing a mixture of metal cations was treated as follows. 1. Dilute HCl was added and a precipitate formed. The precipitate was filtered off. 2. H,S was bubbled through the acidic solution. Again, a precipitate formed and was filtered off. 3. The pH was raised to about 9 and H, S was again bubbled through the solution. No precipitate formed. 4. Finally, sodium carbonate was added and no precipitate formed. What can be said about the presence of...

1. Suppose you are given an unknown aqueous solution that contained one of the following cations AR', Ba", or Na'lons. You have available the following test solutions: 1 M sulfuric acid and 1 M hydrochloric acid. Explain how you would use these test solutions to determine the identity of the cation in the unknown solution. Using complete sentences and proper terms, explain the tests you would perform, the expected outcomes, and how the results would allow you to determine the...

10.0 g of alloy containing only Fe, Cr and Ni when heated with dil. HNO3 dissolved to give Fe3+, Cr3+ and Ni2+ respectively. The resulting solution was diluted to a total volume of 250.00 cm3 by adding distilled water. 25.00cm3 of the diluted solution was treated with excess NaOH and H2 O2 . The obtained precipitate P was fltered and yellow colour fltrate Q was acidifed with dil. H2 SO4 acid, and titrated with 1.0mol dm-3 Fe2+ solution. The volume...
