    at 29:00 isnt the conc of H+ ions = 2 x conc of acid instead of conc of acid = 2 x conc of H+ ions?

    Thank you so much for the video sir, It's an Absolute Life Saver. However I just have one doubt If you dont mind clearing up. At 1:22:29 Why is Dissociation of the Salt an equilibrium, Isn't it Fully Dissociating so It just be an Arrow point to the right. I'm Most probably wrong but it would be helpful if you could clear it up. Thanks alot

    at 41:05 shouldn't the answer for the concentration of methanoic acid be 2.96x10^-11 moldm^-3 instead of 2.96x10^-3 moldm^-3

    I think at around 1:50:00 there's a typo - methanoic acid only has HCOOH, not CH3COOH - but it doesn't matter for the calculations right?

    1:04:08 How here in weak acids you are saying that [H+]=[acid] isn't that only applies to strong bases and acids whereas the weak acids we use the Ka like u have explained in your slide in the green box in 34:38 ? Plz help :) But thanks soo much for your video and for your massive hard work , your videos help me to a great extent :)

    • @stardreamix786
      @stardreamix786 11 месяцев назад

      yeah i was stuck here too, what would you say, would you say that [H+] = sqrt(Ka * [Acid] to rearrange for H+?
