Consider that steam distillation is not an option.need this answer in detail. don't copy elsewhere I will downvote . A separation of the mixture of substances X and Y is carried out by extraction of Craig using an organic solvent of the same volume. What is the dissolved Y fraction in the 18th tube after 24 times of removal if Dy = 5 is knownThe experiment wAs preformed using a recrystallization of salicylic acid. The IR was preformed using a KBR pellet method Re-state the diagnostic peaks from the results, this time with the intention of comparing the experimental to literature diagnostic values as well as fingerprint regions to provide evidence to answer your hypothesis. After comparing your values, you must discuss what conclusions you obtained (i.e. was there evidence to support that your compound is pure?)
- Describe and explain the effect(s) on your result for the following possible experimental errors. In each case, specify the component(s) whose percentage(s) would be too high or too low and explain your rationale why these would be changed. (a) After adding DCM to the counterfeit pharmaceutical at the beginning, you didn’t stir or shake the mixture before filtering. (b) Washing the sucrose recovered during the first vacuum filtration with water rather than DCM. (c) During the NaHCO3 extraction, you failed to mix the organic and aqueous layers thoroughly. - B (d) You mistakenly extracted the DCM solution with 5% HCl rather than 5% NaHCO3. (e) You neutralised the NaHCO3 solution to pH7 rather than pH2.Based on the resulting chromatograms after visualization with iodine vapor, which between the solvent systems WHITE and MIX resulted in a more effective separation of the pigments of the indigo extract? Explain your answer in terms of the solvent that did not effectively separate the components of the root extract.What is the structure and IUPAC name of atrazine? The herbicide simazine is more polar than atrazine. In reverse phase chromatography of a solution containing a mixture of the two substances, which would elute first?
