Solution \So*lu"tion\ (s[osl]*l[umac]"sh[ucr]n), n. [OE.       solucion, OF. solucion, F. solution, fr. L. solutio, fr.       solvere, solutum, to loosen, dissolve. See {Solve}.]       1. The act of separating the parts of any body, or the             condition of undergoing a separation of parts; disruption;             breach.                         In all bodies there is an appetite of union and                      evitation of solution of continuity.   --Bacon.          2. The act of solving, or the state of being solved; the             disentanglement of any intricate problem or difficult             question; explanation; clearing up; -- used especially in             mathematics, either of the process of solving an equation             or problem, or the result of the process.          3. The state of being dissolved or disintegrated; resolution;             disintegration.                         It is unquestionably an enterprise of more promise                      to assail the nations in their hour of faintness and                      solution, than at a time when magnificent and                      seductive systems of worship were at their height of                      energy and splendor.                           --I. Taylor.          4. (Chem.Phys.) The act or process by which a body (whether             solid, liquid, or gaseous) is absorbed into a liquid, and,             remaining or becoming fluid, is diffused throughout the             solvent; also, the product reulting from such absorption.          Note: When a solvent will not take in any more of a substance                the solution is said to be saturated. Solution is two                kinds; viz.: (a) {Mechanical solution}, in which no                marked chemical change takes place, and in which, in                the case of solids, the dissolved body can be regained                by evaporation, as in the solution of salt or sugar in                water. (b) {Chemical solution}, in which there is                involved a decided chemical change, as when limestone                or zinc undergoes solution in hydrochloric acid.                {Mechanical solution} is regarded as a form of                molecular or atomic attraction, and is probably                occasioned by the formation of certain very weak and                unstable compounds which are easily dissociated and                pass into new and similar compounds.          Note: This word is not used in chemistry or mineralogy for                fusion, or the melting of bodies by the heat of fire.          5. release; deliverance; discharge. [Obs.] --Barrow.          6. (Med.)             (a) The termination of a disease; resolution.             (b) A crisis.             (c) A liquid medicine or preparation (usually aqueous) in                   which the solid ingredients are wholly soluble. --U.                   S. Disp.          {Fehling's solution} (Chem.), a standardized solution of             cupric hydrate in sodium potassium tartrate, used as a             means of determining the reducing power of certain sugars             and sirups by the amount of red cuprous oxide thrown down.                      {Heavy solution} (Min.), a liquid of high density, as a             solution of mercuric iodide in potassium iodide (called             the Sonstadt or Thoulet solution) having a maximum             specific gravity of 3.2, or of borotungstate of cadium             (Klein solution, specific gravity 3.6), and the like. Such             solutions are much used in determining the specific             gravities of minerals, and in separating them when             mechanically mixed as in a pulverized rock.          {Nessler's solution}. See {Nesslerize}.          {Solution of continuity}, the separation of connection, or of             connected substances or parts; -- applied, in surgery, to             a fracture, laceration, or the like. [bd]As in the natural             body a wound, or solution of continuity, is worse than a             corrupt humor, so in the spiritual.[b8] --Bacon.          {Standardized solution} (Chem.), a solution which is used as             a reagent, and is of a known and standard strength;             specifically, a normal solution, containing in each cubic             centimeter as many milligrams of the element in question             as the number representing its atomic weight; thus, a             normal solution of silver nitrate would contain 107.7 mgr.             of silver nitrate in each cubic centimeter.
