WebIn 1923, G. N. Lewis proposed a generalized definition of acid-base behavior in which acids and bases are identified by their ability to accept or to donate a pair of electrons and form a coordinate covalent bond. A coordinate covalent bond (or dative bond) occurs when one of the atoms in the bond provides both bonding electrons.

WebIntroduction. The purpose of this lab is to experimentally determine the equilibrium constant, K c, for the following chemical reaction:. When Fe 3+ and SCN – are combined, equilibrium is established between these two ions and the FeSCN 2+ ion. In order to calculate K c for the reaction, it is necessary to know the concentrations of all ions at equilibrium: [FeSCN … WebIn chemistry, iron (III) refers to the element iron in its +3 oxidation state. In ionic compounds (salts), such an atom may occur as a separate cation (positive ion) denoted by Fe3+. The adjective ferric or the prefix ferri - is often used to specify such compounds — as in "ferric chloride" for iron (III) chloride, FeCl3.
