IB Chemistry

• Study plan until IB Exam Nov 2021:
  • For now, topics 8-11 are still disastrous for me.
    • I will use Kognity to clarify any uncertainties and solve Pearson WS.
    • (This is the minimum requirement)
    • I probably have a vague understanding, but I need to consolidate it by summarizing in notes or something.
    • Then, I will focus on memorizing the details.
      • Anki, which I received from (aka), seems to be versatile for this. I’m grateful for it.
  • After that:
    • Solve Pearson challenge problems.
    • Solve Cambridge Textbook Problems.
    • Solve Past Papers 1 and 2.
      • However, I feel that understanding the concepts is a bigger issue than time allocation, especially for Chemistry.
      • So maybe it’s not necessary to time myself solving past papers?
        • Well, but as understanding deepens, I will be able to solve more questions, so time might become tight.
      • It seems important to concentrate and work on these topics.
      • Regardless of what I do, the goal is to fill in as many gaps as possible. So solving past papers might be killing two birds with one stone.
      • Notation:
        • v: Solved all, not checked yet.
        • ~: Solved partially, not checked yet.

• Online Period Notes:
  • There are many past papers for P1 and P2 that I completed hastily.
  • I struggle with the ones I completed hastily or left blank, so I want to cover those later.

• Guide:

  • https://www.ibchem.com/root_pdf/Chemistry_guide_2016.pdf

• First, I will solve the copied versions of Pearson for all subjects and clarify any uncertainties.

• Then, I will do the Mock exams.

  • I might also solve Pearson’s Challenge problems.
  • Since I don’t have them with me, I might borrow the textbooks from school and use zala.

• Chapter 8:

  • I haven’t fully understood it yet, so it seems better to go through it again later.
  • pH/pOH values are for when a substance dissociates into ions.
  • The fact that pH+pOH=14 is because as pH increases, the equilibrium shifts to the left (the side where the substance doesn’t dissociate) due to Le Chatelier’s principle.
    • Originally: A small amount of H2O is already dissociated, almost in equilibrium on the left side.
    • When an acid is added and pH increases, the equilibrium shifts to the left and pOH decreases.
      • For a strong acid, pH increases by the same amount as its concentration, for a weak acid, it increases slightly less.
