Problem

The following questions refer to the titration curve given below.  For each of the following questions circle the correct answer.

           a) The titration curve shows the titration of

  i. a strong acid with a strong base                             ii. a weak acid  with a strong base        iii. a strong base  with a strong acid                          iv. a weak base with a strong acid

                                 

b) Which point on the titration curve represents a region where a buffer solution has formed?

            point A                          point B                          point C                          point D

c) Which point on the titration curve represents the equivalence point?

            point A                          point B                          point C                          point D

d) Which of the following would be the best indicator to use in the titration?

     i. erythrosin B  pK= 2.9                      ii. methyl red pK   = 5.4                                                iii. bromthymol blue pK= 6.8             iv. o-cresonphthalein pK  = 9.0
