On these pages you'll find *optional* supplementary notes for Chem165. I keep stressing *optional* just so that in case I give some information which is not given in lecture, you know that it's not going to be tested. That said, most of the things I write (unless those are answers to some questions) I consider relevant for *understanding*, so it may be worth looking at them. If you have any questions about anything in these notes, please feel free to email me: [email protected]. ## Announcements - Remember that I hold Office Hours on Tuesdays 4:30-5:30pm (SCL21) and Fridays 4-5pm (SCL23). ## Changelog - **Feb 26, 2024:** what happens to [[Alizarin]]? - **Feb 25, 2024:** notes on [[Calculating Any pH]] and [[Brønsted-Lowry Acid-Base Theory]]. Also, check out the interactive figures I made for [extent of dissociation and pH of monoprotic acids](https://demo.ischemist.com/teaching/dissociation-extent), [extent of dissociation for polyprotic acids](https://demo.ischemist.com/teaching/polyprotic-alphas), and [buffer solutions](https://demo.ischemist.com/teaching/henderson-hasselbach). - **Feb 24, 2024:** notes on [[Brønsted-Lowry Acid-Base Theory]] and [[Calculating pH for monoprotic acids]] - **Feb 23, 2024:** notes on [[Arrhenius Theory of Acids and Bases]], [[When Equilibrium meets Arrhenius]] - **Feb 22, 2024:** notes on [[Acids and Bases Overview]] and [[Question 3, Section 5]] - **Feb 13, 2024:** notes for [[Review for Exam 1]] - **Feb 9, 2024:** notes on [[Problem-Solving Strategies]] - **Feb 7, 2024:** notes on [[Le-Chatelier Principle]] - **Jan 31, 2024:** notes on [[Multi-step Reactions (Lecture 6)]] which repeat the argument made in class and provide an alternative, completely optional mathematical & rigorous derivation. Also notes on [[Chemical Equilibrium (Lecture 7)]] which **I strongly recommend!** - **Jan 30, 2024:** notes on the [[Transition State]] -- probably the best note I've written so far! - **Jan 26, 2024:** notes on Arrhenius law and optional derivation of Collision Theory - **Jan 25, 2024:** some updates to Integrated Rate Laws and notes for Lecture 4 - I attach the copy of the [[Introductory Email]]
