Why do we use ethanol, and not water to remove the OpaDry coating from pills?
when we convert benzophenone into benzophenone oxime, why do we use ethanol as a solvent?
Why did we have to use hot ethanol for the recrystallization
B) Why do we state that the Teflon sheets do not completely remove friction in our cement cube testing? (3 points)
2. Why do you suppose a mixture of water -ethanol instead of water alone is used in the process of saponification? 3. Why is stearic acid less soluble than soap? 4. Sodium ethanoate (CH3COO- Na+) and sodium propanoate (CH3CH2COO- Na+) have poor soap capabilities. Why?
Explain why dichloromethane is a good solvent to remove the fat from the milk? Can you use organic solvent like ethanol to replace dichloromethane in this experiment?
How would the conductance of pure ethanol differ from tap water? Why?
In our lab, we will be preparing ethanol from the fermentation of sugar with the help of enzymes present in yeast. "An ethanol concentration of 12% or higher is toxic to yeast; therefore distillation is required to produce ethanol in higher concentrations, In this experiment, ethanol will be produced from sucrose (table sugar) and yeast, and the restulting fermentate will be distilled to produce an ethanol-water mixture that is typically at least 90% ethanol. Note that 100% ethanol cannot be...

Question 4: Look at the 4 solvents that you tested and the possible structure of the unknowns. Is there one solvent that you think might dissolve all these compounds at room temperature? Which one and why does it make sense in terms of IMF. (Hint: "like dissolves like "+...
