WebFor example if pKa = 4, then pKb = 10, and if pH = 11, then pH > pKb > pKa. I think you're thinking of pOH > pKb, in which case pH would indeed be < pKa (if pOH = 11, then pH = 3 < 4). Only time this wouldn't apply is when pKb > pKa, which I'm not 100% sure ever happens so I'm gonna ask in another post lol.

Web(1) calculate moles and use them in your ICE table, so you'd have 0.20 mol CH3COOH and 0.10 mol NaOH as your initial values OR (2) use molarity in your ICE table, but you'd first need to calculate the concentration of the mixture.

Web- Kb = 1.8 x 10^-5 therefore pOH is around 5 - Since the Kb is 1.8, it must be a little bit more positive (aka less negative) than 1x10^-5 so it must be between 4 and 5 - The purpose of the log(4) = 0.6 and log(5) = 0.7 is to show that as the number you're applying log to increases, so too does the answer to that log. dynamics of sexual abuseWebMar 21, 2024 · 4-H Adult Volunteers -.
