A weak acid- strong base titration was performed as follows: 10.00 mL of 0.10 M acetic acid were collected in an Erlenmeyer flask, and then diluted to 100 mL with distilled water. After that, two drops of indicator were added. Then, the buret was filled with 0.100 M NaOH. The titration was started by slowly adding NaOH to acetic acid. (Note: The volume of two drops indicator is ignored as it is so tiny compared with 100 mL.) What is the pH of the solution in the Erlenmeyer flask after adding 6.00 ml of 0.100M NaOH? Select one: a. 5.0 b. 5.2 c. 3.98 d. 4.92
