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
