【正文】 that depends on the relative numbers of solute and solvent particles Colloid: colloidal dispersion, a substance made up of suspended particles larger than most molecules, but too small to be seen in an optical microscopy Sol: solid particles suspended in a liquid, such as mud Gel: solid particles, usually very large molecules, unite in a random and intertwined structure that gives rigidity to the mixture Emulsion: particles of a liquid suspended in another liquid Foam: tiny bubbles of gas suspended in a liquid Aerosol: air or gas is the suspending medium colloid equilibrium constant equilibrium constant: K is equal to the product of the concentrations of the reactions products, each raised to the power equal to its stoichiometric coefficient, divided by the product of the concentrations of the reactants, each raised to the power equal to its stoichiometric coefficient Reaction quotient: Q, takes the same form as K but is used for reaction not at equilibrium Electrochemistry Electrochemistry: deals with oxidationreduction reactions that either produce or utilize electrical energy Electrochemiscal cell: in which an electrochemical reaction occurs Halfcell: each electrode and its surrounding electrolyte voltaic cell: generates electrical energy from a spontaneous redox reaction Electrolytic cell: uses electrical energy from outside the cell to cause a redox reaction to occur.
