Paul Andersen explains how acid-base chemistry can be understood in terms of equilibrium.  Water is present in all acid-base chemistry and is amphoteric in nature.  The Ka and Kb values can be used to determine the strength of an acid or a base.  Titrations can be used to student neutralization reactions between strong and weak acids and bases.

The video resource "Acid-Base Reactions in Solution: Crash Course Chemistry #8" is included in the "Chemistry" course from the resources series of "Crash Course". Crash Course is a educational video series from John and Hank Green.

Acetic Acid to Acetyl Chloride mechanism. Can be generalized to forming any acid halide from a carboxylic acid

Paul Andersen explains pH as the power of hydrogen. He explains how increases in the hydronium ion (or hydrogen ion) concentration can lower the pH and create acids. He also explains how the reverse is true. An analysis of a strong acid and strong base is also included.

Actinium is element number 89, and first of the actinide series. This video is one of the 118 clips included in the periodic table of elements themed collection created by Brady Haran and the University of Nottingham in the UK.

In this video Paul Andersen explains how the activation energy is a measure of the amount of energy required for a chemical reaction to occur. Due to the collision theory the activation energy requires proper energy and orientation of the colliding molecules.
