sentences:  Salting-out salts increase the self-hydration of water through hydrogen bonding and reduce the hydration of the copolymers, thus reducing the critical micelle temperature and critical micelle concentration.Salting-in electrolytes reduce the water self-hydration and increase the polymer hydration, therefore increasing the critical micelle temperature and critical micelle concentration.The different salts have been categorized by the Hofmeister series according to their ‘salting-out’ power.
