Every great chemistry teacher has a stoichiometry toolbox full of lessons designed to chisel away at misconceptions and confusion. It's time to make room for something new! Incorporate a brief but detailed video that walks junior...

Start stoichiometry scholars off on the path to success with a short video. The narrator of this interesting video guides viewers through the concepts of the mole, molar mass, and Avogadro's number. Additional topics include converting...

Does a concentrated solution or a diluted solution contain more particles? The 24th video in a 30-part series answers this question as an introduction to figuring concentration using the standard formulas. Through two different formula...

Explore titration endpoint calculations. After first explaining the process, the instructor introduces calculation problems. He illustrates the calculations necessary for figuring the pH of a solution at the equivalence point.

If you are trying to make laughing gas, N2O, and you make N2O5 instead, you now have a highly dangerous chemical. So how do you control what you make when they have the same ingredients? The 14th video in a series of 29 explains how...

Moles are so important to chemistry that Michael Offutt composed an entire musical album titled Molennium about them. The video walks through how to use moles to solve a couple of different equations. It explains each step and when you...

Theory versus reality strikes again — only this time, scholars figure how close they come to each other. Video explains how to use the numbers for theoretical yield and actual yield to determine the percentage yield of various...

When does 2+1=2? When calculating in moles, you sometimes have calculations that appear to defy basic math. The 13th video of 29 explains the pairing and combining of molecules and how to calculate their molecular masses. It also details...

One mole of a substance is equal to the molecular mass of the same substance. A video explains how to solve for the ratio of atoms to particles in a compound. It walks through a couple of example problems using moles to ensure viewers...

Bring an informative resource to your unit on acids and bases with a video that explains strong and weak acids, pH scales, acids in solutions, dissociation, and dilution. 

What is a mole? How do you convert moles to grams, as well as from grams to moles? Check out this short video to find the answers to these and other pressing questions.

Studying acids and bases can be basic. Over the course of four short videos, an instructor explains the pH scale. Viewers observe a demonstration and watch the instructor solve two quiz questions in detail. 

Two plus two is four, but how can two liquids come together and form one solid? Learn how ions can mix in solutions and fall out to form a solid in precipitation reactions through discussion and analysis of cations, anions, and...

Take a deep breath before watching this video from PBS Digital Studios that models for viewers how humans are connected through the air we share. The video explores how small the earth's atmosphere is compared to the rest of Earth.

How do you tell a plumber from a chemist? Ask them to pronounce unionized. The first video in the set demonstrates the pH and conduction of ions based on their acid and base strengths. The next two videos are quizzes that apply the...

What happens when you mix a strong base into a strong acid and the resulting pH change? Explore this reaction with a demonstrative chemistry video. This is the ninth video in a series of 13.

Scholars first learn about Le Chatelier's principle with a two-video set. They then apply their knowledge to a short quiz. 

The Ideal Gas Law isn't always ideal. Learn about situations where gases behave differently and calculate those changes by using van der Waals' equation.

Moles exist in chemistry? These are not animals that live underground and dig through your gardens — they are quantities of elements. Learn about moles and how they help chemists determine amounts of substances (from atomic mass to grams).

A chemistry instructor explains titration with strong acids and bases in a series of three videos. Learners then demonstrate their understanding with two short quizzes. This is the eighth set of videos in a series of 13 sets.

Focus on the basics of solubility in chemistry with an explanatory video, which focuses on how to solve solubility problems and common ion effect calculations. 

Can you crush a soda can using only the air around you? Use an engaging video to teach about the relationship between pressure, volume, moles, and temperature of a given gas, all done with the Ideal Gas Law.
