Understanding ADH and the Control of Water Balance in the Body
This video explains the role and function of ADH (anti-diuretic hormone) in controlling the body's water balance. It describes how ADH is produced and released from the pituitary gland in response to changes in the body's water content,...

Solubility Product Constant (Ksp)
We've learned that some ionic solids are totally water insoluble, but in fact this is a slight oversimplification. Even such solids will dissolve to some minuscule degree, and we can measure this, and do calculations with it. Let's learn...

Acid-Base Equilibria and Buffer Solutions
Remember those pesky iceboxes? Weak acids and bases establish equilibria, so we have to do iceboxes to figure out things about them. But don't worry, buffers are neat.

Calculating Ion Concentrations in Solution
We know that concentration is typically expressed with molarity, which is moles per liter. But how do we know how many moles of solute are present in solution when an ionic solid dissolves in water? It's not so simple because these will...

How To Do Titration Calculations
Titration experiments enable you to work out the concentration of an unknown solute, when you know the concentration of another solute. After carrying out the experiment, you have to do some calculations. In this video we run through...

The Chemistry of Air Purification
It's amazing to think that we've gone from having no idea what air is, to knowing its composition intimately, and even having the ability to filter what's in it. We have produced machines that can remove both pathogens as well as harmful...

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...

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!
