Acid-base chemistry can be extremely confusing, particularly when dealing with weak acids and bases. This set of lessons presents an updated view of the Brønsted-Lowry theory that makes it easy to understand answers to common questions: What's the fundamental difference between a strong acid and a weak acid? Can acid A neutralize base B? Why are some salts acidic and others alkaline? How do buffers work? What governs the shapes of titration curves? This complete rewrite of the previous 1996 pdf document is now organized into seven lessons covering all aspects of the subject. Much emphasis is placed on the practical aspects of calculations, including how to deal with quadratic equations and how to judge when approximations are appropriate.

sci KNOCKHARDY PUBLISHING produces notes and other resources for AS and A2 Level Chemistry. The module references are for the AQA and OCR examinations but the material applies equally well to other specifications. The pages are saved as PDF files and may be freely read and printed for personal use but they may not be revised or circulated in any other form without the consent of Knockhardy Publishing. JONATHAN HOPTON Chemistry 101 - Introduction and Index of Topics By Anne Marie Helmenstine, Ph.D. Updated March 16, 2016. Welcome to the world of Chemistry 101! Chemistry is the study of matter. Like physicists, chemists study the fundamental properties of matter and they also explore the interactions between matter and energy. Chemistry is a science, but it is also used in human communication and interaction, cooking, medicine, engineering, and a host of other disciplines.

General Chemistry for Students The basics What is Chemistry all about? An introduction to chemical science. This tutorial attempts to present the major concepts that define modern chemistry, without, of course, getting into the gory details! The unit concludes with an illustrated summary of the main currents of modern chemistry. Basic Chemistry – Introduction to Chemistry Course Description This free online course offers a simple introduction to basic chemistry and is ideal as a study aid for secondary school students or anyone interested in learning the basics of chemistry. Topics covered include the periodic table, atoms and molecules, the pH scale and experimental design and techniques.

Introduction to Solutions Introduction to Solutions Return to Solutions Menu A solution is a particular type of mixture. Chemistry Powerpoints NOTE: As of May, 2014 I am displaying these PowerPoints in the unit organization that we will begin using in the 2014 - 2015 school year. Of course, you are welcome to use them in any order you choose. This page contains links to the PowerPoint presentations that I will be using in class. Though I place them here to give my students 24/7 access, they may also be used by any teacher or student who can benefit from this resource. I have found that it is much easier to incorporate small, topical presentations into my course. Also, I believe that these become more useful to other teachers when I allow you to organize topics as you choose.

How it Works? The immune system has two parts – 'innate' and 'adaptive' Innate immunity The 'innate' (meaning: "present from birth") part of the immune system is so-called because it has a number of set strategies for recognising and dealing with certain kinds of infection, without needing to be "trained" to identify them. This generally involves certain immune cells "sniffing-out" germs, via signs in the bloodstream, following the trail to the site of infection, and neutralising the invaders with special chemicals before swallowing them (a process known as 'phagocytosis').
