• Fromyour work explain if phenolphthalein is the proper indicator forthe titrations.

• Usingyour textbook as a reference, choose an appropriate indicator foreach titration. Justify your answer.

• Consider the pH at theequivalence point for each of the titrations. Why are theydifferent? Why aren’t they all at pH=7.00?

• Whatwould the titration curve look like if 0.1 M NaOH were in the buretand 0.10 M HCl were in the flask? Make a rough sketch to illustrateyour answer.
