4. Properties of Amines: Solubility, Basicity and Amine Salts Place 3 drops of triethylamine in a test tube. Cautiously note the odor of the amine by fanning the vapor with your hand toward your nose. Odor Now add 2 ml of DI water. Observe the solubility. Check the pll of the solution. Write an equation that shows the amine has been ionized as a weak base in water. Name the...

3. To the solution from step 2 add 6 M NaOH, sodium hydroxide solution, drop-by-drop until the solution is just basic to litmus paper. Note the odor of the solution. Write an equation to show that the amine salt is converted back to the amine, which is called the free amine or free base. Odor Chemical Equation Disposal: Discard the solution in the waste container. 5. Base Hydrolysis of Amides 1. Place...

using the procedures, we used dichloromethane as the unknown
mixture and i was able to extract benzoic acid for an acid,
5-chloro-2-methoxyanaline for a base compound and biphenyl for
neutral compound.
i don't know if that answers the missing part but if it didn't
could you be specific please? thank you!
2. Construct a flow chart of the acid-base extraction you carried out. Use the specific structure of the compounds isolated. Don't use the molecular formula. (15 pts) We used...

Part III. Single Replacement. With the following reactions, evidence of a reaction may not be immediately apparent. Before making a decision be sure to let the reaction stand for approximately 10 minutes. If no reaction occurs, write, "NO RXN" in under balanced chemical equations; Do not Wrile products or other equations. 1.

Question:
Procedure Separation and Identification of Pb2 (aq), Fe (aq), Al(a), and Cu Note: Tests should be performed concurrently on the known and the unknown solutions. Volumes are approximate. All work excepting the centrifugation should be done in the fume hood 1. To about 2. mL of your sample in a test tube, add 5 drops (-0.2 mL) of 6 M HCl(a). Mix well and centrifuge. Decant the clear liquid into a clean test tube and save it for Step...

if a reaction is Oxidation reduction or not. Thanks a lot
OXIDATION-REDUCTION Introduction Chemists refer to reactions which involve a transfer of electrons from one reactant to another as oxidation reduction reactions of just "redox" reactions. Oxidation is defined as a loss of electron and reduction as a gain of electron by a substance during a chemical reaction. The loss of electrons by one substance...
