For the lab practical experiment, you will be given a 1.00-8 sample of benzophenone contaminated with benzoic acid. Your task is to write your own protocol and complete as much of it as possible in a 2-hour period, with the objective being to obtain a pure sample of benzophenone in the highest percent recovery. Techniques to consider when writing your protocol include the following: • Recrystallization...

How would a mixture of naphthalene and benzophenone behave on a TLC plate with hexanes / acetone as the eluent? Compare the polarity of these two compounds. Outline the most commonly used procedure for the purification of an impure solid material using the technique of recrystallization. Why is acetone such a popular solvent? Point out one drawback in terms of safety considerations. Your final product might be impure since you suspect decomposition might have occurred. When determining the melting point...

What is the unknown solute in a solution of benzophenone with using freezing point depression? In this lab, the test tube with the solution was put in a hot water bath on a hot plate. The test tube was in a beaker. Mass of benzophenone: 6.863 g Mass unknown: 0.752 g I placed benzophenone in a test tube in the hot water bath. Once it melted, I recorded 48.5 C. I stirred the test tube and the temperature lowered to...

(5) During step 13 (TLC) of Part 4, a student switches the order of lanes 1, 2, 3 and 5. They are confident only in the identity of lane 4-the recrystallization filtrate. After running the TLC plate with 7:1 petroleum ether- diethyl ether, they obtain the following plate: А в с Lane 4: Recrystallization Filtrate (a) Assign A, B, C, and D to each of the following: initial crude product, triturant, solid after trituration, and purified triphenylmethanol. (b) Historically, most...

Hello, i did a lab where i was given a sample of contaminated water
and must determine the identity of the metals and must percipitate
one out. I was able to determine the identity of metal Y which is
aluminium and metal X which is lithium. Im confused on part 3
though. lithium and alumnium are soluble in almost anything and i
cant use hydroxide or carbonate since lithium is in there, some
