Term | Definition |
---|---|
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 |
