so would it be like pH = pKa + [A-]activity coeff / [HA]activity coeff
I'm not sure which activity coefficient would be on top and bottom
but more importantly I am uncertain on how to use the Debye-Hückel equation.
I found ionic strength using I=1/2 sum(con*charge^2), but in the equation I'm not sure what the charge would be since I have two ions in my compound and also not sure what atomic size i would use. Since they arent charged compounds im not even sure if im going in the right direction.
