You would recrystallize benzoic acid using water as the solvent rather than methanol. Explain why.
You would recrystallize benzoic acid using water as the solvent rather than methanol. Explain why.
Explain why one would recrystallize a solid from a solvent pair instead of a single solvent. Explain how it works in terms of solubilities.
1. Can benzoic acid be recrystallized using Dichloromethane as a solvent instead of Water. Justify your answer. 2. Benzoic acid purified using recrystallization melted at 10 oC less than its actual M.P. Is the sample pure? List possible errors that could have happened during the recrystallization. 3. Where in the IR spectrum of benzoic acid would you expect to find the C=O and C=C bond?
When doing the Recrystallization of benzoic acid. Is it better to use just water as the solvent or with methanol and water as a solvent pair? Why and what are the differences?
Why is water solubiilty of benzoic acid significantly less than the water solbilty of the benzoate ion? Briefly explain and relate to the partition coefficient (kD).
503 50 Sp> arb) sps se 9. Explain why phenol is substantially more acidic than methanol, but benzoic acid is not much more acidic than acetic acid. Phenol is more acidic than methanol " Mars methanol benzolo OH
In the preparation of methyl benzoate from benzoic acid, methanol, concentrated H2SO4, and heat, why is methanol used as the excess reagent? Thank you
12) Water was found to be a suitable solvent for recrystallization of benzoic acid. How should the solution of benzoic acid be prepared during the recrystallization? a. by dissolving the solid in a maximum volume of the boiling solvent b. by dissolving the solid in a minimum volume of the boiling solvent C. by adding 10 ml of hot solvent, in small portions to the solid and stirring until the solid dissolves x d. by adding 10 ml of the...
Assume the solubility of benzoic acid in ice-cold water is 1.70 g/L and the solubility of benzoic acid in hot water is 68.0 g/L. Calculate the minimum volume of water (in mL) needed to recrystallize 0.800 g of benzoic acid.
You react benzoic acid with methanol and sulfuric acid catalyst. a) Draw the structure of the product and b) give the name of the functional group you produced
You have 100 mL of a solution of benzoic acid in water; the amount of benzoic acid in the solution is estimated to be about 0.30 g. The distribution coefficient of benzoic acid in diethyl ether and water is approximately 10. Calculate the amount of acid that would be left in the water solution after four 20-mL extractions with ether. Do the same calculation, using one 80-mL extraction with ether, to determine which method is more efficient.
