CHE 131 Study Guide - Midterm Guide: Molar Attenuation Coefficient, Sodium Chloride, Molar Concentration
Document Summary
Earths surface is ~ 751. covered by water. Properties of water are responsible for life on earth and many geographical features. All natural waters have tonic and molecular compounds dissolved in them solutions homogeneous mixtures of 2. + substances solvent component of a solution that is present in the greatest amount solute component in a solution other than the solvent. Aqueous solutions water is a solvent concentration amount of solute in a particular amount of solvent / solution amountofsolu-e-opamoun-ofsolt. tt# amount of solvent amount of solution of lower concentration stock solution concentrated ; used to prepare solutions. Dilution process of lowering concentration of a solution by adding more solvent. Dilution doesnt changes moles of solution only volume * " m m solute =\/ m m g = ( lx -2 m9_ ,) Strong electrolytes ~ 100% dissociated into 10ns . Weak electrolytes only partially dissociate into 10ns. Non electrolytes no ionization occurs ;no conduction of electrical current.
