If one takes a solid containing a small amount of impurities and dissolves it in a suitable solvent to form a saturated solution at elevated temperature, the impurities are likely to remain in solution when the solution is cooled and the solid crystallises out. Solutions of Electrolytes Solutions of electrolytes are the electrically conducting solutions formed when salts are dissolved in water. The high electrical conductivity of the solution is due to the presence of ions from the dissociation of the salt. Solvation Solvation is the interaction of ions of a solute with the molecules of the solvent. It occurs only with polar solvents.
Solvation is the process that causes ionic solids to dissolve in polar solvents.
The energy released during solvation is sufficient to compensate for the lattice energy of the ionic crystal, in which the ions are arranged in the solid state. A solvent is a liquid that dissolves another substance or substances to form a solution. The spectrum of hydrogen is obtained by an electrical discharge in a Geissler Tube . The spectrum contains four bright lines, due to atomic hydrogen and is used in calibrating spectroscopes and refractomeres. This spin quantum number, s relates to the spin on an electron.
