- for (4) and (5) please provide reactants and why it was chose1. Explain the problem with each of the following techniques. The sodium hydroxide solution was not mixed thoroughly after diluting with deionized water. A student fails to swirl the Erlenmeyer flask during the addition of NaOH solution during the titration.please create a flow chart using my reactions above I posted an example of what it should look like: thank you
- The question is: Consider a mixture containing 0.5 benzil and 0.05 biphenyl. Your task is to isolate the benzil in pure form. Would this be best accomplished by recrystallization or extraction? I don’t really know which one would be better cause both can isolate a substance in its pure form. Thanks!Should your calibration curve go through the origin? Why? Or why not? in the solubility lead iodine lab experimentFor the following reactions, draw arrow-pushing mechanisms for each of the reactions that (a) extracted them into the aqueous layer and (b) forced them to precipitate out. Acidic compound precipitated after the addition of HCl.
- Calculate the molecular weight from the titration data. What does that suggest about how many nitro groups were added?Kiko, a Chem 31.1 student, accidentally shuffled two test tubes with different compounds on his way to the laboratory. To confirm the possible identities of the compounds, Kiko added neutral KMnO4 and Lucas reagents to both test tubes labeled A and B. Test tube A gave a brown precipitate in neutral KMnO4 while test tube B produced a purple solution in the same test. Upon subjecting to Lucas Test, both test tubes produced layers. Which of the following are the possible identities of the compounds A and B? a. Sec-butanol and 3-methyl-3-pentanol b. n-propanol and tert-butanol c. isopropyl alcohol and 4-nitrophenol d. hexanol and cyclopentanolGive the (general) chemical reactions of each test and underline the product that is observable (i.e., positive test indicator) 1.
