Heating Curves, Buffers & Standard Enthalpy of Formation

In this live, I'll go over how to find the heat absorbed using a heating curve, we'll also go over how to find the pH of a buffer when adding base or acid. Plus we'll go over standard enthalpy of formation and how to properly use the formula.

💁‍♀️ HI I'M MELISSA MARIBEL
I help students pass Chemistry. I used to struggle with this subject, so when I finally graduated with a bachelor's degree in Chemistry, I became a tutor so that you wouldn't have to struggle like I did. I know that with the right help, YOU CAN LEARN ANYTHING!

    Is buffer can be weak base and conjugate acid?

  • @Sir.Veresta
    @Sir.Veresta2 жыл бұрын

    i'm doing a Ph buffer problem and it has hno2 on top instead of no2- in the Ka expression, why? wouldn't it be h3o+=Ka (no2-/hno2) instead of h3o+=Ka (hno2/no2-)? hno2=0.50 M, no2-=0.75M is it because of cocentration?
