    Starting my first semester as a Toxicology Biochem grad and I'm going in with only an undergrad degree in biology with no experience in organic or biochem, so I've a lot of catching up to do. These early sorts of concepts are novel to me, but the way you explain them is so easy to follow and helpful! Thank you so much for helping to take the stress out of things!

    Ive been going through your acid-base titration and buffer videos and they are super helpful thanks
    I have two questions though: Can you not have a WB:CA buffer? and how would you calculate SA:WB buffer?
    Thanks again

    • @triple_gem_shining
      @triple_gem_shining Місяць тому +1

      Wb/ca buffer is the same as a wa/cb buffer. That's the DEFINITION OF A BUFFER!
      As for SA/WB buffer yes. But it's in a 1:2 ratio. Half of the wb is neutralized. Reverting back to 1:1 of the two conjugates

    @saqibkhan3364 Рік тому +1

    Hello Chad, this was a great lesson. Definitely one of the harder concepts for me as I study for the MCAT. Question for you: As you state, a buffer is composed of a weak acid and its conjugate base or a weak base and its conjugate acid. Because a weak acid has a strong conjugate base and vice versa, could we say that a buffer is composed of a weak acid and a strong base and/or a weak base and a strong acid? Might have to rewatch some sections. I hope my question makes sense. Thanks for all your help

    • @saqibkhan3364
      @saqibkhan3364 Рік тому +1

      For example, around 22:45, you say something along the lines of, "you can use the Kb expression because you also have a weak acid's weak conjugate base." But I thought from previous lessons, that a weak acid will have a strong conjugate base and vice versa. Why is it different in this case?

    • @kathode1
      @kathode1 5 місяців тому

      saying its composed of a weak acid and a strong base would imply that it’s actually a strong base like NaOH, KOH, etc and vice versa. you’ll be safer just saying a weak acid/base and their conjugate base/acid

    Hi Professor Chad. I appreciate your content. Quick question, you mentioned common detractors @21:12 and state that 0.1M solution of HF and a 0.1M solution of NaOH won't make a buffer, but what if it's a 2:1 volume ratio in favor of HF ?

    • @ChadsPrep
      @ChadsPrep  9 місяців тому

      In this type of question you may be provided the volumes and concentrations of the solutions that are being mixed (what you are suggesting) or you may be provided with the final concentrations of the resulting solution (what I was referring to). You can typically tell the difference and the biggest clue is often whether or not volumes are provided. Hope this helps!
