4. Rinse out your jars once again. Place a very small amount (about 1/8 tsp.) of baking soda (NaHCO3) into a jar. Pour some vinegar (CH3COOH) onto the baking soda and observe. Google this if you do not have the substance. a. What happened? b. Is there any baking soda remaining? Yes/No If you answered yes, pour some more vinegar on it. Can you make it disappear completely? c. Where did the baking soda go? d. How?

Experimental Procedure HAZARD: Sulfuric acid, acetic anhydride and glacial acetic acid are corrosive to the skin. They are also irritants, and all operations in which these substances are used should be carried out under the hood. Prepare a hot-water bath by heating a 400-ml beaker containing about 200 mL of water. 1. Use a centigram balance and...

What is the limiting reagent in this experiment? Acetophenone or
aqueous bleach?
1. Add about 1.0 g (measured accurately) of acetophenone to 40 mL of the bleach solution (5% NaCl in water - this reactant should be included in your table of reagents!) in a 100 mL round bottom flask equipped with a magnetic stirrer. Clamp the flask in the fume hood above a stir plate. 2. After the initial reaction has subsided, boil the reaction mixture gently for 5...

What is the SN2 reaction? How does Br attach to which carbon as
a nucleophile and why? Difference between Unimolecular or
Bimolecular? How NaBr and H2SO4 work in the
reaction? Why Water/Sulfuric Acid/Brine/Sodium
Hydroxide/Na2SO4 in Extraction? What does
each layer have inside in each step of the separation?
Please help. Due to corona, this is a theoretical lab and I am
very confused.

PROCEDURE CAUTION!!! Nitric acid and sulfuric acid are strong and corrosive acids. For that reason, avoid inhaling its vapors or causing any contact with the skin or clothing. Wear your protective glasses at all times. Use the extractors to work with these acids. A. Nitration of methyl benzoate 1. Preparation of the reactants. In the extractor you will find a burette with concentrated sulfuric acid, a second burette with concentrated nitric acid, clearly identified. Familiarize yourself with the scales of...
