4) In a titration of a 100.0mL 1.00M HA weak acid solution with1.00M NaOH, what is the pH of the solution after the addition of49.5 mL of NaOH? Ka = 1.80 x 10-5 for HA. (3significant figures)
**Remember to calculate the equivalence volume and think aboutin which region along the titration curve the volume of base falls,region 1, 2, 3, or 4**
5) In a titration of a 100.0mL 1.00M HCl strong acid solutionwith 1.00M NaOH, what is the pH of the solution after the additionof 30.9 mL of NaOH? (3 significant figures)
**Remember to calculate the equivalence volume and think aboutin which region along the titration curve the volume of base falls,region 1, 2, 3, or 4**
