What Are Standard Conditions?
Sometimes we do chemistry or take measurements at something called "standard conditions". What does this mean? It refers to a particular temperature and pressure, since these are factors that will often affect the experiments we do....

Predicting Precipitation With Ksp Values
Now that we know about the solubility product, it's time to learn about some applications for this concept. First, we can use this to predict whether precipitation will occur in a particular solution, and take measures to cause or...

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...
