A 150 mL solution of NaOH is titrated with HI. Phenol red is the indicator, which is red at high pH values and yellow at low pH values. The indicator be [ Select ] when you first put it into your analyte, before any titrant is added. The indicator will be [ Select] at the endpoint. The indicator will be [Select] V if you overshoot the endpoint and add too much acid.
Consider a titration in which 4.50M sodium hydroxide (a strong base) is being used to titrate 250.0mL of 0.200M acetic acid (a weak acid). Instead of titrating to full neutralization, we want to know when the pH = 5.000. We have the right indicator to give us a color signal when we get to 5.000--predict how many mL of 4.50 M sodium hydroxide we will need to add. pKa, acetic acid = 4.75
