Electrolyte
Compound that conducts an electric current in aqueous solution
Nonelectrolyte
Compound that does not conduct electric current in aqueous solutions
Hydrate
Compound that contains water of hydration
Hygroscopic
Compound able to remove moisture from air
Desiccant
Drying agent
Suspension
Mixtures from particles settle on standing
Colloid
Heterogeneous mixture containing particles of medium sized (between suspensions and solutions)
Surface tension
Inward force that tends to minimize the surface area of a liquid
Surfactant
Intermolecular attraction between a hydrogen atom and a highly electronegative atom such as oxygen in an adjacent molecule
Ice
Solid form of water
Aqueous solution
Dissolved in water
Solvent
Dissolving particles in solution
Solute
Dissolved particles in a solution
Solvation
Process that occurs when absolute dissolves
Tyndall effect
Scattering of visible light by colloidal particles
Brownian motion
Chaotic movement of colloidal particles
Solution
Solute dissolved in solvent
Miscible
Two liquids that dissolve in each other
Immiscible
Two liquids that don’t dissolve in each other
Molarity
Number of moles of solute dissolved in a solution
Boiling point equation
100+(0.52)(moles solute)
Ionic solids will dissolve in what
Water because it is a polar solvent
Concentration equation
(Grams solute)(grams solvent) = ppm
What happens when NaCl is added to H2O
Boiling increases, freezing decreases
Ionic compounds conduct electric currents when
Dissolved in water
