A chemist has synthesized a monoprotic weak acid and wants to determine its Ka. He dissolves 2.00mmol of the solid acid in 100.0mL water and titrates the resulting solution with 0.0500M NaOH. After 20.0mL NaOH has been added, the pH is 6.00. What is the Ka value for the acid. 13 3. A buffer is prepared by adding 50.0mL of 0.220M NaOH to 100.0mL of 0.15M acetic acid, HAc. What is the pH of the resulting buffer solution?
