This stuff makes me hate high school 
The 5 people that disliked the video are the ones that didn't look at the comments about where the Ka of 1.8*10^-5 came from

is it appropriate to use Henderson-Hasselbalch equation?

What if I don't know Ka of Kb? I have a hw problem that asks us to find pH at equilibrium, and I have an awful teacher.

THANK YOU SO MUCH. This video cleared so much up for me. Thank you thank you thank you!!
Hypochlorous acid (HOCl) is a weak acid with pKa = 7.54. A 45.00 mL sample of 0.240 mol L-1 HOCl solution is titrated with a 0.250 mol L-1 standard KOH solution. What is the pH at the equivalence point? Would you be able to do this? I'm not getting the answer my prof is sayin
you cant use the ICE table is its not in equilibrium....??

how did u get 0.01 mols of naoh to begin with?
