10 mL of NaOH were added to the funnel in order to extract the organic layer into a flask labeled Organic Layer.

Naphthalene benzoic acid chemical formula. EPA has classified naphthalene as a Group C possible human carcinogen. Benzoic acid with NaOH 7. The C stands for carbon and the H stands for hydrogen.

Write a balanced equation for the acid-base reaction that occurs when the carboxylic acid component of your mixture was extracted from the methylene chloride solution. Naphthalene the simplest of the fused or condensed ring hydrocarbon compounds composed of two benzene rings sharing two adjacent carbon atoms. The chemical molecular formula of naphthalene is pretty easy to remember.

In general the total change in enthalpy Δ H is given as the change in internal energy Δ U plus any pressure-volume work Δ PV that accompanies the process. Molecular Formula C 7 H 6 O 2. Average mass 122121 Da.

Benzoic acid has a pKa of 417 while 2-naphthol has a pKa of 95. C 7 H 6 O 2. Since benzoic acids pKa is lower.

C6H5COO- Na H2O. Therefore benzoic acid is said to be an aromatic carboxylic acid. Monoisotopic mass 122036781 Da.
