Abstract

The dissociation constants for benzoic and p-chlorobenzoic acids were measured in aqueous solution, and the constants for benzoic, p-chlorobenzoic, p-bromobenzoic, p-iodobenzoic, p-toluic, p-ethyl benzoic, and p-cuminic acids were measured in 80% alcoholic solutions by means of a quinhydrone electrode.

A description of the electrode, and the vacuum tube amplifying circuit used in connection with the potantiometer, is given.

The synthesis of p-toluic, p-ethyl benzoic, and p-cmninic acids is described.
