Khan Academy: P Ka and P Kb Relationship

A video focusing on the Ka and Kb relationship. Explore the relationship of the pKa and pKb and the conjugate acids and bases with example problems. [14:33]

How the Henderson-Hasselbalch equation can be used to look at the ratio of conjugate acid and base using relationship between buffer pH and pKa. [7:50]

Cause and Effect is the second concept in the Next Generation Science Standards. The video highlights both the mechanisms and explanation for cause and effect. It also discusses universality and scale as they relate to the topic.

Recognize the relationship between Gibbs free energy, reaction quotient Q, and cell voltage. [12:31]

This tutorial demonstrates deriving the relationship between pKw, pH, and pOH. Calculating the pH or pOH of strong acids and bases. [14:49]

Learn about the autoionization of water, the autoionization constant Kw, and the relationship between [H+] and [OH-] in aqueous solutions.

In this article, read all about the relationship between spontaneity and equilibrium to the Gibb's free energy change.

This video illustrates and explains how seismic waves function. These waves are broken down into two types: surface and body. Take a look into why waves help understand the structure of Earth. [8:38]

Sal Khan introduces the circulatory system function and the structure and function of the heart. [14:53]

See some examples of calculating pH of 0.25 M solution of sodium acetate, and calculating the pH of 0.050 M solution of ammonium chloride. [14:15]
