Lewis Acid-Base Theory

    DOWNLOAD  $0.99



    The ‘Lewis Acid- Base Theory’ app discusses the theory which rests on the principle that a substance which accepts an electron pair is called a Lewis acid, and the one which donates an electron pair is called a Lewis base. The app describes how the Lewis Theory attempts to offset the flaws characterizing other acid-base theories and also lets you derive the conclusion that a strong acid is not the same as a concentrated acid or base.
