Caq – Substance’s Concentration in the aqueous phase

“Caq” or substance’s concentration in the aqueous phase refers to the concentration of a chemical in the aqueous phase.

This term is a parameter used to determine the amount of dissolution of a chemical in aqueous media and is important in environmental assessments to analyze the rate of dissolution of a chemical into water. It helps to estimate the potential impact of a chemical on the ecosystem, especially in toxicity and exposure assessments.
