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. And finally, in the final step, I solve for that PH by using the formula 14 equals poh plus PH. Now, if you don't know where this formula comes from, check out the link right there. So basically rearrange and find my PH.
