The determination of the freezing point of a solution is a critical operation in food engineering, cryopreservation, and chemical processing. In concentrated systems, the presence of solutes lowers the chemical potential of water, depressing the ice formation temperature. This calculation is essential for refrigeration system design, shelf-life stability prediction, and phase-change management.
