a) . The jar into which salt is added will show a clear solution while the jar with wheat flour will show a suspension solution (having white particles of wheat flour in the solution which will settle down after sometime).
b). Because salt is soluble in water and it mixes with water completely that is why jar with salt forms clear solution, on the other hand wheat flour is insoluble in water and remains as it is that's why jar with wheat flour have a suspension solution on shaking .
2. Rinse out your jars and fill them 3/4-full with clean water. Sprinkle a small amount...
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?
QUESTIONS TO ANSWER: Prepare a table of all chemicals used with the structure and purpose of each. Calculate the theoretical yield by finding limiting reactant of the experiment by converting reactants to product (remember to show all calculations used) Calculate the percent yield using the limiting reactant Calculate the Rf for triphenylmethanol. If there are two dots, determine which one is triphenylmethanol.. ( I did not provide data. Please let me know how I Would do this if I did)...
Prelab questions:1. Make sure the reaction table described above is completed in your notebook.2. Two benzaldehyde molecules combine with one acetone molecule in this aldol reaction. If someone uses 5.0 mL of benzaldehyde and 2.5 mL of acetone to try to improve the yield of product, is this the correct ratio of molecules so that there is no excess? Why or why not?The Aldol Reaction: Synthesis of DibenzalacetonePurpose: Introduce the student to the hands-on chemistry of carbonyl condensations.Warning: Dispose of...
