Ion Exchange in Concentrated Solutions. III. Magnesium Chloride-Hydrochloric Acid and Aluminum Chloride-Hydrochloric Acid Systems

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...

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...

Enthalpies of Dilution of Aqueous Electrolytes: Sulfuric Acid, Hydrochloric Acid, and Lithium Chloride

Calorimetric meas urements at 25°C of th e enthalpies of dilution of aqueo us H2S04 (0.00090 to 6.4 mol · kg-I ), LiCI (0.026 to 6.7 mol · kg-I ), and HCI (0.018 to 1.6 mol· kgI) have bee n performed us ing two different isothermal calor imeters. The result s of thi s work and that of three ea rli e r calorimetri c in vestigations and one Raman spectral investigation have been used to calculate...

Chemical changes in cutin obtained from cuticles isolated by the zinc chloride-hydrochloric Acid method.

The composition of Malus pumila Mill. cutin from cuticles isolated using ZnCl(2)-HCl reagent has been compared to that isolated by an oxalate-enzymic method. Molecular changes were observed and included the loss of unsaturated components and hydroxyl groups. Such changes may alter the results of physiochemical investigations of cuticles.
