A solution containing a mixture of metal cations was treated as outlined. 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. A precipitate formed and was filtered off. What can be said about the...
Another form of this equation (called the complete ionic equation) indicates the species that are actually present in solution. 2Na+ + CO32-+2hr + 2 cr . 4 co2 +H2O + 2 Na. + 2 cr Since balanced chemical equations indicate only substances that change, this equation simplifies to This simplified equation is called a net ionic equation. The evolution of CO2 gas is visible as tiny bubbles. Sulfate, so2 Sulfate, So,, is found in compounds such as NaSO4. If a...

LAB DESCRIPTION: In aqueous solutions the Ni2+ cation forms a complex ion with 6 H2O ligands. The formula of this complex ion is: Ni(H2O)62+. When this complex ion is mixed with aqueous NH3 a reaction occurs where some of the H2O ligands are displaced with NH3 ligands. But how many of the H2O are displaced by NH3? In this experiment you will mix nickel(II) sulfate and aqueous ammonia to synthesize a compound containing a complex ion whose formula is Ni(H2O)6-x(NH3)x2+,...
