Use the Henderson-Hasselbalch equation.
I understand that is the equation but I can not figure out how I get the numbers. I know the equation is
ph= pka + log [salt]/[acid]
I know pka is -logKa but I do not know how to get the numbers for the [salt] or the [acid] to divide. I have an extremely
HORRENDOUSLY bad college professor who pretty much says he is trying to weed out the potentially bad nurses that cannot do these things.
