If 20 mL of 0.10 M NaOH are added to 30 mL of 0.20 M HOAc, what is the pH of the resulting solution? (Ka = 1.8 ยด 10-5 for HOAc.)
Answered by DrBob222
Write the balanced equation, calculate the moles HOAc remaining and the moles NaOAc formed, then used the Henderson-Hasselbalch equation to solve for pH.
