Ka Constant

Postby lukezhang2C » Fri Nov 30, 2018 10:35 am

Do we need to know how to calculate the Ka equilibrium of acid/base reactions?

Dr. Lavelle said no, calculating equilibrium constant is covered in 14b.

Two qualitative things that would be useful to know include
1) Ka and Kb deal with the ratio of concentrations
2) Products sit on top of reactants, meaning a stronger acid/base, which dissociates more easily, will have a greater Ka/Kb

Ka is the concentrations of the products over the concentration of the reactants, but I'm not sure if we will need to know how to calculate it.

No, but along with what others mention, just know that higher Ka --> lower pKa = stronger acid, higher Kb --> lower pKb = stronger base.
