Please right an
in depth discussion about part C. We we’re not able to get any
recrystallization from our unknown. Talk about possible failures
that could of happen that prevented us to not get any or our
unknown to recrystallize. Thanks so much!
Experiment 1: Solids: Recrystallization and Melting Point Learning Outcomes: Upon completion of this lab, students will be able to perform the technique of recrystallization of an impure solid as well as be able to determine an appropriate...
How does rate of crystal growth effect the purity of a recrystallized compound? during recrystallization, what effect would impurity have on melting point of benzoic acid?
A sample of benzoic acid, which should be pure white, was found to have a grayish color after recrystallization. The melting point was correct, and the melting point range was small. Explain why the melting point was still correct and occurred over a narrow range in spite of the grayish tint.
why isnt the benzoic acid answer?꙼̈
melting points of Benzoic acid and Phenyl succinate are both
121 celsius in the chart. can you please explain?꙼̈
1. An unknown compound X is one of the four compounds listed in the following table. A mixture of X with benzoic acid melts at 89°C, a mixture of X with phenylsuccinate melts at 20°C, and a mixture of X with m-aminophenol melts at 102°C. What is the identity of X? Explain Chemnical mp. ("C)...

prepare a flow sheet for the preparation of benzoic acid from a) bromobenzene and magnesium and b) phenylmagnesium bromide and carbon dioxide. using your knowledge of the physical properties of the solvents, reactants, and products, show how the products can be purified, indicate which layer should contain the product in the liquid/liquid extraction steps.
Please, write out the balanced chemical reactions used to sequentially extract the carboxylic acid and the phenol from the organic phase into aqueous phases, and then precipitate them upon acidification of the aqueous phases, using the information below. 1st) You will prepare an ether solution (the organic phase) of the two compounds; any minor impurities are non-acidic and will remain dissolved in the organic phase throughout the extraction process. 2nd) You will extract benzoic acid from the organic (ether) phase...
I
think this question is regarding hydrolysis, so it breaks into
aldehyde/ketone/carboxylic acid group(?) but I'm not entirely
sure.
