When choosing which indicator to use in a titration reaction, you should consider:
what color you would like to see at the end point of the titration
the relative strengths of the acid and base you are using in the titration
how long the titration will take to complete--------
adjusting the end point of the titration to better match your indicator
When a small amount of acid is added to a buffer, the weak base form of the buffer is converted to:
its weak conjugate acid form
its strong conjugate acid form
its strong conjugate base form------
an even weaker base form
Buffers are systems that resist changes in pH by converting strong acids or bases to weak acids or bases.
