Distribution Coefficients of Zinc Ion and Hydrogen Ion in the System, Zinc Chloride-Hydrochloric Acid-n-Butanol-Water

Isolation of Plant Cuticles With Zinc Chloride-hydrochloric Acid Solution.

rhe cuiticle of plants is a heterogenous memnbranie in which wax, pectin and cellulose in varying l)ro)ortions are contained in a cutin franmework. In the isolation of cuticular membranes from leaves or fruits the wax is nornially removed by extraction xvith ani organic solvent before detachment of the memnbranes from the underlying epidermal cells. Detachnmenit is achieve(d by the use of eithe...

Improved Rigid Ion Model of Molten Zinc Chloride

We have developed a new rigid ion model for the simulation of molten ZnCL. A molecular dynamics simulation of this model under a constant pressure of 1 atm and a constant tempera ture of 1200 K resulted in a successful description of the short-range order in the liquid state. The resulting short range structure is presented with respect to the coordination of the Zn 2+ ions and the Z n C I Z n ...

Hydrogen chloride / hydrochloric acid Toxicological overview

Health effects of acute exposure • The main routes of exposure to hydrogen chloride are via inhalation, or skin or eye contact and exposure to hydrochloric acid is predominantly by ingestion, or skin or eye contact • Inhalation may cause irritation to nose and upper respiratory tract, ulceration, coughing, chest tightness and shortness of breath. Higher concentrations cause tachypnoea, pulmonar...

Localization of Hydrogen Ion and Chloride Ion Fluxes in Nitella

Alternating bands of acid and base formation have been detected along the length of the internodal cell of Nitella clavata when it is illuminated, while in the dark this phenomenon is minimal. Chloride influx occurs only or largely in the acid-extruding regions, and this is also a light-dependent ion movement. Chloride efflux is slightly dependent on illumination and is not localized as are H(+...
