Question

How could you separate a solution of benzoic acid and tetradecane? Use words to explain please. Boiling points are too similar to use.

Answer 1

Answer #1

1. dissolve both compounds in ether. (benzoic acid is active and tetradecane is nutral compound) and take in separating funnel.

2. add aq. bicarbonate solution to the mixture , shake the separationg funnel for 5 min. separate the aq. layer.

3. benzoic acid comes into aq. layer, and tetra decane remains in the ethar layer.

4. add aq. Hcl solution to the aq. layer and obtained ppt was filtered to get benzoic acid.

Ph cooH + NaHCO3 ....> Ph COONa + CO2+ H2O

Ph COONa + HCl .........> PHCOOH + NaCl

5. organic layer evoparated to get tetra decane.

please help! 4. Describe how to separate a mixture of phenol, benzoic acid, and toluene using aqueous NaHCO3, aqueous NaOH, and ether. NaOH can separate the shenol and NaHCO3 can be used for benzoic acid because it dissolved in it. Toluene will be more difficult because it doesn't dissolve in noot or Nation, but the ether can be used for it.

(a) Calculate the ratio of dissolved benzoic acid to benzoic ion that will exist in solution at equilibrium at pH of 2.00. The acid equilibrium constant (Ka) for benzoic acid is 6.46x10^-5. Note that this calculation doesn't account for the benzoic acid that has precipitated from solution, but you can assume that the higher the ratio, the more benzoic acid will precipitate. (b) Carry out the same calculation for a pH of 4.00, and explain why it was important to...
