TermDefinition
dissociation the separation of an electrolyte into ions of opposite charge
equilibrium state of a chemical reaction in which its forward and reverse reactions occur at equal rates so that the concentration of the reactants and products does not change with time
indicator any of various substances, such as litmus or phenolphthalein, that indicate the presence, absence, or concentration of another substance by means of a color change
Neutralization a reaction between an acid and base that yields a salt and water
saturated Combined with or containing all the solute that can normally be dissolve at a given temperature
Acid any of a class of substances whose aqueous solution are characterized by a sour taste, that ability to turn blue litmus red, and a ph less than 7
Ionization Formation of ions by heat, electrical discharge, radiation, or chemical reaction
Miscible Can be mixed in all proportions
salt chemical compound formed when hydrogen of an acid is replaced by a metal.
Unsaturated capable of dissolving more of a solute at a given temperature
Supersaturated to cause a chemical solution to be more highly concentrated than is normally possible under given conditions of temperature and pressure
nonelectrolyte a compound which, dissolved in water, does not separate into charged particles and is incapable of conducting an electric current
PH a measure of the acidity or alkalinity of a solution, numerically equal to 7 for neutral solutions, increasing with increasing alkalinity and decreasing with increasing acidity & uses scale of 0-14
Neutral of or relating to a solution or compound that is neither acidic nor basic
solute a substance dissolved in another substance, usually the component of a solution present in the lesser amount
aqueous relating to, similar to, containing, or dissolved in water
solvent a substance in which another substance is dissolved, forming a solution
Immiscible cannot undergo mixing or blending
electrolyte a chemical compound that ionizes when dissolved to produce an electrically conductive medium
base any of a class compounds whose aqueous solutions are characterized by a bitter taste, a slippery feel, the ability to turn red litmus blue, and a ph greater than 7
