And that's exactly what we do. So in my second step, I basically use the KB or the base annette and constant. I equate that to my equilibrium expression, which states that the concentration of hydroxide, what I'm looking for, equals the concentration of the conjugate acid over the concentration of the conjugate base. Now, I could get this guy in this side and divide by this guy and get the concentration that I'm looking at equals a known constant, unknown amount, and a known amount. Now I solve and I find my concentration. Next, I find my poh by using the formula which is negative lot of the concentration found here in step three.
