OpenStudy (joannablackwelder):
pKa = -log Ka where Ka is the ionization constant
OpenStudy (joannablackwelder):
Do you know how to solve for Ka?
OpenStudy (aaronq):
you can also use the henderson-hasselbalch equation for a shortcut pH=pKa+log[A-]/[HA]
OpenStudy (anonymous):
yes i understand how to get the ka and ph concentrations, but i need to find out how to set up the values to get the ionization percent
OpenStudy (joannablackwelder):
Ahh, I see. I don't remember how to do it exactly and don't have time to remind myself at the moment. I did find an example that you may find helpful. http://answers.yahoo.com/question/index?qid=20091222061041AAWzvKL
