Equivalent \E*quiv"a*lent\, n.
   1. Something equivalent; that which is equal in value, worth,
      weight, or force; as, to offer an equivalent for damage
      done.

            He owned that, if the Test Act were repealed, the
            Protestants were entitled to some equivalent. . . .

   2. (Chem.) That comparative quantity by weight of an element
      which possesses the same chemical value as other elements,
      as determined by actual experiment and reference to the
      same standard. Specifically:
      (a) The comparative proportions by which one element
          replaces another in any particular compound; thus, as
          zinc replaces hydrogen in hydrochloric acid, their
          equivalents are 32.5 and 1.
      (b) The combining proportion by weight of a substance, or
          the number expressing this proportion, in any
          particular compound; as, the equivalents of hydrogen
          and oxygen in water are respectively 1 and 8, and in
          hydric dioxide 1 and 16.
