This paper introduces a molecular-dynamics workflow that simplifies and robustly computes the solubility of molecular or ionic crystals. This method is considerably more straightforward than the state-of-the-art, as we have streamlined and optimised each step of the process. Specifically, we calculate the chemical potential of the crystal using the gas-phase molecule as a reference state, and employ the S0 method to determine the concentration dependence of the chemical potential of the solute. We use this workflow to predict the solubilities of sodium chloride in water, urea polymorphs in water, and paracetamol polymorphs in both water and ethanol. Our findings indicate that the predicted solubility is sensitive to the chosen potential energy surface. Furthermore, we note that the harmonic approximation often fails for both molecular crystals and gas molecules at or above room temperature, and that the assumption of an ideal solution becomes less valid for highly soluble substances.","lang":"eng"}],"file":[{"relation":"main_file","file_id":"14620","content_type":"application/pdf","access_level":"open_access","date_created":"2023-11-28T08:39:06Z","file_size":6276059,"checksum":"f668ee0d07096eef81159d05bc27aabc","creator":"dernst","success":1,"date_updated":"2023-11-28T08:39:06Z","file_name":"2023_JourChemicalPhysics_Reinhardt.pdf"}],"scopus_import":"1","has_accepted_license":"1","department":[{"_id":"BiCh"}],"oa_version":"Published Version","citation":{"ieee":"A.
