| acid-base balance | The normal balance between acid and base in the blood plasma, expressed in the hydrogen ion concentration or pH, resulting from the relative amounts of acidic and basic materials ingested and produced by body metabolism, compared to the relative amounts of acidic and basic materials excreted from the body and consumed by body metabolism; the normal state of acid-base balance is not one of neutrality, with equal concentrations of hydrogen and hydroxyl ions, but a more alkaline state with a certain excess of hydroxyl ions.

| balance | 1. An apparatus for weighing. In its simplest form, a balance consists of a beam or lever supported exactly in the middle, having two scales or basins of equal weight suspended from its extremities. Another form is that of the Roman balance, our steelyard, consisting of a lever or beam, suspended near one of its extremities, on the longer arm of which a counterpoise slides. The name is also given to other forms of apparatus for weighing bodies, as to the combinations of levers making up platform scales; and even to devices for weighing by the elasticity of a spring. 2. Act of weighing mentally; comparison; estimate. "A fair balance of the advantages on either side." (Atterbury) 3. Equipoise between the weights in opposite scales. 4. The state of being in equipoise; equilibrium; even adjustment; steadiness. "And hung a bottle on each side To make his balance true." (Cowper) "The order and balance of the country were destroyed."

| balance theory | In social psychology, a theory which assumes that steady and unsteady states can be specified for cognitive units, such as an individual and his or her attitudes or acts, and that such units tend to seek steady states (balance); e.g., balance exists when both parts of a unit are evaluated the same, but disequilibrium arises when both parts are not evaluated the same, which causes either cognitive reevaluation of the parts or their segregation. See: cognitive dissonance theory, consistency principle. (05 Mar 2000) |
