When 0.025 L of 2M WHAT is added to it.
Use the Henderson-Hasselbalch equation and set up an ICE chart with it. If you will show your work I can help you through it.

Do i use Ka or Kb?
Answered by DrBob222
The HH equation uses pKa. Don't have pKa? Remember to convert Kb to pKb, then
pKa + pKb = pKw = 14
