Using an ICE table to calculate molar solubility. [8:15]

Using examples this videos explores the equilibrium constants of Ka and Kb. Learn what these constants can tell you about the concentrations of acids and bases in a chemical reaction. [14:33]

See the Bronsted-Lowry definition of acids and bases explained, and learn how to conjugate acids and bases. [8:57]

This lesson will define reaction rate as the change in concentration of products (molarity) in a chemical reaction over time.

This lesson will explain that when an equilibrium is disturbed, the reactants and products will respond in such a way as to re-establish the equilibrium. Identify that changes in concentration, temperature, pressure, and volume can...

This lesson demonstrates how to calculate parts per million (ppm). It is 1 of 2 in the series titled "Parts per Million Calculations."

In the following video Paul Andersen explains how disturbances to a reversible reaction at equilibrium affect the equilibrium constant and the reaction quotient. For example if the concentration is changed the reaction will move to...

Calculate the concentration of weak base using information about equivalence point in a titration. This example is from the 2015 AP Chemistry free response question 3b. [6:16]

Learn about divided attention, selective attention, inattentional blindness, & change blindness in this Khan Academy video. [6:41]

A concentration gradient occurs when the concentration of particles is higher in one area than another. In passive transport, particles will diffuse down a concentration gradient, from areas of higher concentration to areas of lower...

Kinetics is the study of reaction rates and how they are affected. Many factors, such as concentration, pressure, temperature, and enzyme activity, can impact the rate of a reaction. [15:27]

Learn how to calculate the unknown concentration with titration. See an example of titrating strong acid, hydrochloric acid, with strong base barium hydroxide. [7:49]

This video is an introduction to acid-base titrations using example of titrating 20.0 mL of HCl of unknown concentration with 0.100 M NaOH. Covers indicators, endpoint, equivalence point, and calculating the unknown concentration.
