The solubility of phenazine-1-carboxylic acid (PCA) in water, methanol, and ethanol solutions was measured over the temperature range of (278.2 to 328.2) K. The solubility of PCA in methanol and ethanol is higher than that in water and increases with increasing temperature in the three solvents. All measurements were correlated with the Apelblat equation. The equation was found to provide an accurate representation of the experimental data.
