Before starting a titration equation, what do we need to find? - ANS-Ka/Kb (given the other), volume, 
concentration of acid and base, initial mols of weak acid/base 
at the starting point of a titration, how do you find pH? - ANS-use a RICE table to find K expression 
equation, plug initial (not titrant) concentration into table and when you have K expression, solve for X. 
take -log of x for pH 
at the buffer region of a ti...
