2)Make a rough plot of pH versus milliliters of acid added for the titration of 50.0 mL of 1.0 M NaOH with 1.0 M HCl. Indicate the pH at the following points and tell how many milliliters of acid are required to reach the equivalence point. a)Before the titration starts b)At the equivalence point c)After an additional 10.0 mL of HCL is added after the equivalence point (i.e. equivalence point volume + 10.0 mL)
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
