A buffer solution contains 0.403 M NH4Br and 0.320 M NH3 (ammonia). Determine the pH change when 0.078 mol KOH is added to 1.00 L of the buffer. The answer is .19. But I have no idea how find Ka for this problem, so I can't even begin. I know you're supposed to find Ka first, then use the henderson-hasselbach equation, then ICE. If someone can go in depth into finding the Ka to this and then guiding me through the rest of the steps, I'd be eternally grateful
