Carboxylic Acids and Derivatives

CCA! Volume 5

About CCA!

Conductivity of carboxylic acids, pH of acetic acid derivatives, hydrophobic effect, and soap emulsions of hydrocarbons are demonstrated.

The conductivity of carboxylic acid solutions is tested with a conductivity apparatus.

The pH of acetic acid, monochloro-, dichloro-, trichloro-, and trifluoroacetic acids are compared.

Hydrophobic Effect: Octanoic acid forms a monolayer on the surface of water under certain conditions.
