- Nickel carbonyl, Ni1CO24, is one of the most toxic substancesknown. The present maximum allowable concentrationin laboratory air during an 8-hr workday is 1 ppb(parts per billion) by volume, which means that there isone mole of Ni1CO24 for every 109 moles of gas.

- What are relative advantages and disadvantages of organicsolvent,aqueous two-phase, and supercritical-fluid extraction for recovery of bioproducts?Can embedding nanoparticles of silver intoa polymer give the polymer antimicrobialproperties?synthetic ion exchange resins. These resins are organic polymeric networks that contain functional groups that are permanently attached to the resin. One such functional group is sulfonic acid, -SO3H. When placed in water, the resin (being a large organic molecule) will not dissolve. However, the ionic functional groups become hydrated and the resin will swell as it takes up waters of hydration. The resin may then be thought of as a solid solution mixture with the functional groups being "dissolved" but the polymer remaining as a solid. The hydronium ion (H3O+) associated with acidic functional groups like sulfonic acid will dissociate just as it would if the acid were free of the resin. If other cations such as Cu2+ or Na+ are added to the resin, an ion-exchange reaction can occur: . Note that one H+ is released for each positive charge bound to the resin. Since the resin exchanges a hydrogen ion for a sodium ion in this reaction, sulfonic acid resins are called cation-exchange…
