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.
Why is phthalic acid better recrystallized in water solvent rather than using ethanol or diethyl ether as solvent for the phthalic acid?
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...
The solubility of benzoic acid in water at 20C is 0.0029g / mL, and at 100C it is 0.068g / mL. Calculate the amount of water needed to recrystallize 1.00g of benzoic acid at the boiling point of water. procedure*
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.
