Question

What is the pH of the resultant solution if the pKa of an amine is 7.4 and the ratio of nonionized to ionized species is 10:1?

science chemistry

Answer 1

Answer #1

The pH can be determined using Henderson-Heasselbalch equation :

pH = pKa + log[A^-]/[HA]

= 7.4 + log(1/10)

= 7.4 -1

= 6.4

% 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.
