What are some necessary safety precautions when working with sulfuric acid?Provide a reasonable reaction procedure to separate each product from the reaction mixture usingthe extraction technique.Provide the balanced reaction for this experiment.
- You've probably noticed by now that the amount of acetic acid consumed wasn't the same in each trial. This is because we have to add enough sodium bicarbonate to react all the acetic acid. If we add too little, we run out of sodium bicarbonate before all the acetic acid reacts and some is left over at the end. Based on what you're seeing, which trials do you think had enough sodium bicarbonate added to react all of the acetic acid? Sample Calculations for Vinegar Lab g HC2H3O2 Consumed by Reaction -2 g NaHCO3 1.98 -4 g NaHCO3 2.78 -6 g NaHCO3 3.14 -8 g NaHCO3 2.87 -10 g NaHCO3 2.93 -2 g NaHCO3 -4 g NaHCO3 -6 g NaHCO3 -8 g NaHCO3 -10 g NaHCO3Answer the following question regarding the pictures please: The information for this set is based off of the column separation of ferrocene and acetylferrocene. D:What makes ethyl acetate a suitable or unsuitable solvent? ethyl acetate is too polar there would be no issues separating the three compounds using ethyl acetate as the solvent ethyl acetate is not polar enough E: What concerns would you have if you were to run a column using hexanes as the solvent for the whole column? hexanes is too polar and there would be no separation for the three compounds hexanes would be a good solvent to isolate all three compounds from the column hexanes is not polar enough to elute diacetylferrocene hexanes is not polar enough to elute any of the compounds no matter how much solvent you use F: Come up with an appropriate solvent gradient to get the best separation of all three compounds, list them first to lastReduction of Vanilina Reduction of Vanilin What is the limiting reagent in this reaction?
