The pKa of phenol (C6H5OH) is 9.95. Suppose that the composition of the mixture somewhere between 25% and 75% NaC6H5O by mass. If 1.000 g of the sample mixture, dissolved in enough water to make 20.00 mL of solution, is going to be titrated with 0.100-M HCl, which of the indicators listed in this lab would be the best for identifying the equivalence point? Justify your answer with clear reasoning and any necessary calculations.
