Define and discuss the Brondsted-Lowry model. Present acids as hydrogen ion donor and a base is represented by being a hydrogen ion acceptor. Show a typical formula as HX (an acid) + H20 (base) ---> H3O^+ + X^- Define and discuss conjugate acids and bases and a conjugate acid-base pair. Example by using hydrogen fluoride and determine why it is Bronsted-Lowry acid and what determines what the conjugate acid and Base molecule would be.
