What is a Strong
acid? What is a
  Weak acid?




     • Strong Acid
          – Complete dissociation
     • Weak Acid
          – Does NOT completely dissociate
          – Have Equilibrium equations because it
            wants to go back to its original state
                            Hydroflouric
 Meet the
                               Acid
Compounds!

             Hydrochloric
                Acid



    Water
 This is the
dissociation    Note the SINGLE arrow! This means
   of HCl.     complete dissocation, which means that
                      HCl is a STRONG acid.
 This is the
               Note the DOUBLE arrows! This means that this acid
dissociation
   of HF.         does not completely dissociate and needs an
                 equilibrium equation. Thus, HF is a weak acid.
Let’s take a look
   inside the
 beaker, shall
       we?
  Now, let’s look
inside the beaker
 again. This time,
   we have real      Note that there is no HCl in the beaker! This is
   molecules.         because it completely dissociates and does
                          not want to go back to its acid form.
   Let’s
 Summarize
     !




• equilibrium equations
    H20         H+ + OH-
    HF + H20        F- + H30+

• dissociation equation
    HCl         H+ + Cl-
