- What effect will the following have on plate height (H). Make sure to explain your full and complete reasoning. Reducing the rate of sample injection.3. Assume that in extraction from water into toulene, analyte A has distribution ratio of 10. A 20 mL portion of an aqueous solution of A is extracted with toulene. Which of thw following procedures will result in most efficient removal of A from the aqueous phase into toulene? (Please show the solution of the correct answer) A. 1 extraction with 20 mL of touleneB. 1 extraction with 40 mL of touleneC. 2 extractions with 20 mL of toulene eachD. 4 extractions with 10 mL of toulene eachDescribe briefly how liquid-liquid extraction can be used to separate (not necessarily 100% separation) an analyte, A, from a potential inference, B in a liquid sample. What must be the most important difference between A and B for the separation to succeed?
- In comparing direct headspace injections with SPMEheadspace injections, later eluting peaks (by GC) arelarger in SPME. Explain why.In a GC run, dodecane was used as test solute for a 30 m x 250 ?m i.d. DB-5 column. The dodecane peak eluted at 5.2 min. and the distance between its two inflection points was 4.0 s. This was the number of theoretical plates generated by this column:As a newly appointed research officer, Marissa has been assigned a task to separate a mixture containing acetone, acetamide and 1,2-dichloroethane using a high-performance liquid chromatography (HPLC) technique. The instrument was equipped with a 40-cm column packed with cyano propyl bonded to the siloxane backbone material. i) List THREE (3) examples of mobile phase solvent/solvent systems that can be used with the column above. ii) Determine the sequence in which the three analytes eluted from the column and explain the underlying principle applied. iii) Sketch the chromatogram that would be produced if the column was replaced with a column filled with C18 hydrocarbon bound to the siloxane backbone material and acetonitrile was employed as the mobile phase. Label the peaks observed.
- Diprivan® (propofol) is a commonly used sedative-hypnotic agent used for sedation and anesthesia during minor as well as major surgical procedures.

Based on what you see below, this prep is most likely a(an): Emulsion Microemulsion Suspension SolutionPls solve this question correctly in 5 min i will give u like for sure What evidence supports or refutes that during an experiment, purified extract is pure caffeine?Extraction of the aqueous salicylic acid solutions with 10% ethyl acetate/hexane (density ~ 0.7 g/ml) will give two layers in the separatory funnel. a. Will the aqueous layer be the upper layer or the lower layer? b. If dichloromethane (density ~ 1.3 g/ml) were substituted for the 10% ethyl acetate/hexane solution, which layer would be the aqueous layer?
- A chemist received different mixtures for analysis with the statement that they contained NaOH, NaHCO3, Na2CO3, or compatible mixtures of these substances, together with inert material. From the data given, identify the respective materials, and calculate the percentage of each component. 1.000g samples and 0.2500N HCl were used in all cases. (A) For Sample W: With PP, 24.32ml was used. A duplicate sample required 48.64ml with MO. (B). For Sample X: The addition of PP caused no color change. With MO, 38.47ml of the acid was required. (C). For Sample Y: To cause a color change in the cold with PP, 15.29ml of the acid was necessary, and an additional 33.19ml was required for complete neutralization. (D) For Sample Z: The sample was titrated with acid until the pink of PP disappeared; this process required 39.96ml. On adding an excess of the acid, boiling, and titrating back with alkali, it was found that the alkali was exactly equivalent to the excess acid added.hree components in a mixture have varying distribution constants between the mobile phase and the stationary phass One of the components has a very low distribution constant, Would this component likely elute first or last and how would you design an experiment or modify the components of the separation to make it perform in the opposite manner?Calculate the amount of phycocyanin in Sample 1 in mg where A620 = 0.193 and A650 = 0.095, taking into account the dilution factor of 100 ul, and the total volume of extract 45ml.
