Expressing Concentration by Mass Percent
We know how to express solution concentration in terms of molarity and molality, but the common public also needs to communicate concentration for certain reasons, and they don't really know about moles and things like that. What do they...

What Is Dynamic Equilibrium?
Learn about dynamic equilibrium, the conditions required for dynamic equilibrium to be reached and examples of systems at equilibrium.

What Are Dilutions
In this video, we will look at what dilutions are in chemistry, how to calculate them using a very easy equation and even extending to multiple dilutions which are called serial dilutions. Dilution is the process of adding water (or...

The Role of ADH in Negative Feedback Mechanisms
The video discusses the concept of negative feedback as a control mechanism that aims to maintain a constant water concentration in the blood. It explains that ADH, a hormone released by the pituitary gland, has the effect of making the...

Kinetics: Initial Rates and Integrated Rate Laws
Who likes math! Oh, you don't? Maybe skip this one. Unless you have to answer this stuff for class. Then yeah, watch this.

Expressing concentration of solutions
It describes the concentration of the solution in terms of mass percentage, volume percentage, parts per million and mole fraction.

Rates of Reaction - Part 2
Learn the basics about rates of reaction. Chemical reactions can only happen if reactant particles collide with enough energy. How do you measure the rates of a reaction? Find out more in this video!
Professor Dave Explains
Molarity and Dilution
Now those pesky moles are swimming! But how much solute is there? Let's learn about how we measure concentrations of solutions.
Professor Dave Explains
Molality and Colligative Properties
Solute particles interfere with the physical processes a solution may undergo. These are known as the colligative processes of a solution. Ever wonder why we put salt on icy streets? Find out here!
msvgo
Ionization of Acids and Bases
It explains the ionisation of acids and bases. It explains the term conjugate acids and bases. It derives the expression to calculate ionic product of water.
msvgo
Stoichiometry
It explains the concept of Stoichiometry, Concentration of Solution, Mole Fraction, Molality & Molarity.
Professor Dave Explains
Neutralization Reactions
We know about acids and bases, and we know about acid-base reactions, so what is a neutralization reaction?

Factors that Affect Diffusion Rate
In this video, we will discuss four factors that affect the rate of diffusion: molecular weight, concentration gradient, surface area-volume ratio, and the temperature.

Exploring the pH Scale and Testing Solutions
In this video, the teacher explains the concept of acidity and pH levels. They discuss the differences between strong and weak acids, as well as dilute and concentrated solutions. The teacher also demonstrates how to test the pH of a...

Chemical Equilibria and Reaction Quotients
Many chemical reactions don't just go one way, they go forwards and backwards. Once there is balance between the two, this is an equilibrium. And we need to be able to predict how much stuff there will be at equilibrium! Get ready to...
