Khan Academy: Ka and Acid Strength

Learn the basics of acids, bases, proton concentration, the pH scale, and buffers in this article.

Resource provides an overview of the steps of the citric acid cycle, also known as the Krebs cycle or tricarboxylic acid (TCA) cycle. Gives detailed examples of how this amazing cycle works and discusses the products of the cycle.

Understand the definition of Bronsted-Lowry acids and bases, strong and weak acids and bases, and how to identify conjugate acid-base pairs.

Define buffers and their compositions, and learn about carbonate buffering systems in nature, acid rain, pH of buffers, and titration. See an experiment using indicators to showcase just how awesome buffers are. [10:51]

A detailed overview of cellular respiration, in particular, the Krebs or citric acid cycle. [17:47]

Learn the basics of the Bronsted-Lowry definition of acids and bases in this video. [8:56]

Video talks about the two main methods of alpha-amino acid synthesis: Gabriel synthesis and Strecker synthesis. [5:23]

Learn how anion size and bond dissociation energies affect acid strength. [5:47]

A video discussing the molecular structure of DNA. Understand that DNA is made up of a phosphate, deoxyribose sugar, and one of the four nitrogen base. Video also explains how the nitrogen bases pair up to form the double helix...

This video will explore the pH scale. See some examples of how to calculate the pH of water, orange juice, and bleach. [11:37]
