    I have to thank you SO much for teaching the acid/base equations this way. It was incredibly helpful. With so many formulas to learn, this method puts everything into perspective and so much easier to understand. FINALLY the pH formulas make sense and are clicking! Thank you thank you!!

    I know this is late, but I noticed there were SEVERAL of you that didn't understand Mr. Post's Step 4. I am right along with you. Seeing that he didn't answer any of the other posts, I took it upon myself to look it up and figure it out. Thought I would share because I know there will be others that are just as confused. Okay, so on step 4 we are also solving for the inverse, or antilog of 10x -11.6 (or maybe just 11.6) Still just a little confused....sigh... Hope this helps. Follow these steps.
    I have a TI30XIIS scientific calculator and solved it in this manner. 1. Press (2nd) 2. Press (Log) 3. Press (-) 4. Press 11.6 5. Press " ) " to close the parenthesis. 6. Press (=) or (Enter) That gives you the inverse or antilog of -11.6 which gives you 2.51 x10-12. The number of H+.

    You did a great job on this video. I'm not always sure how to use my T1-84 C Silver Plus calculator. So, why not buy one and do a whole video just on using that? I'm sure you would do an awesome job. Considering there isn't much out there on using the calculator, but you did a better job than most! Thanks. :) BTW, you cleared it all up on this topic. So thanks so much! M.

      Mallory Durrick Merlino LOL. Great idea on the video, but I'm not familiar with that one. I literally use one like the screen showed. Check out my other vidson this topic if you need more help. Thanks for tuning in :)

    • @mallorydurrick
      @mallorydurrick 9 лет назад

      Well, you got me there anyway. Also, the next day, the teacher showed everyone how to find the -log and antilog on their calculators but I learned from you so I didn't need the help. Passed the test too! Final is tomorrow.

    Hi, I was just wondering about your answer for [OH-] in the question "Calculate the pOH, [H+] and the [OH-] of a HCl solution with a pH of 3.2?" What I was wondering about, because I am taught to be very specific, is your final answer to [OH-], which you got as 1.58x10^-11 which shouldn't it have been 1.587301587x10^-11 => 1.59x10^-11 (3sf) ?
