% Ionization using Henderson Hasselbalch equation ionization given ph and pka: pka:8.0 at a pH of 7.4 what is the percent ionization? Here is what I have so far: pka=pH + log(acid/base) 8.0=7.4+ log (acid/base) 0.6= log (acid/base) 10^0.6= (acid/base) = 3.98 this is where I got stuck. my solution should be 80% but I not sure how. please show all work. Book answer: % acid form = (3.98 x100)/ 4.98 = 79.99 % Where did they get 4.98???
