There are 10 unknown ID's. What compound are the Unknowns?
Clues:
1. Copper sulfate solutions are blue.
2. Acids react with sodium sulfide and release gas. Hydrogen sulfide smells like rotten eggs.
3. When a base is mixed with NH4Cl it will smell like ammonia (NH3).
4. Ammonia vapor will turn litimus paper blue when it is damp.
5. When silver nitrate is combined with compounds containing halogens (Br,Cl,I), white or yellow precipitates form.
6. BaCl2 reacts with H2 SO4 and CuSO4 and forks a white precipitate BaSO4.
7. When CuSO4 is mixed with KI it gives orange-yellow precipitate. No precipitate with NaBr.
8. When excess NaOH is added to BaCl2 white cloudy precipitate ((Ba(OH)) is formed.
9. HCl and AgNO3 react and produce AgCl( white precipitate).
10. AgCl forms white precipitate AgBr forms creamy or light yellow precipitate.
