Why Water Dissolves (Almost) Everything
Water can dissolve more substances than anything else on earth...so why doesn't it dissolve everything away?

Solubility
In this video Paul Andersen explains how the dissolution of a solute in a solution can be explained as a reversible reaction. Bonds in the solid solute are broken and the ions are dissolved in a solution. The Ksp (or solubility product...

Solutions: Crash Course Chemistry
This week, Hank elaborates on why Fugu can kill you by illustrating the ideas of solutions and discussing molarity, molality, and mass percent. Also, why polar solvents dissolve polar solutes, and nonpolar solvents dissolve nonpolar...

Why Is Carbon Dioxide Mixed In Cold Drinks And Beverages?
One of the most important factors when it comes to mixing any gas with a liquid is solubility, and carbon dioxide is highly soluble in water. In fact, it's the most soluble of the common, non-toxic gases with high solubility. To give you...

Solubility Rules: Predicting Solubility of Compounds in Water
The video discusses solubility rules and how to determine whether a salt or compound is soluble or insoluble in water. State symbols are introduced as a way to determine the state of chemicals or species in a reaction. The video then...

Free Energy of Dissolution
We've learned a lot about solution chemistry, and we've also learned about thermodynamics and spontaneity. So what about the spontaneity associated with dissolution? If an ionic solid dissolves in water, is this an enthalpically or...

Why Do Bubbles Form In A Glass Of Water?
Water especially the one which flows through the pipe contains atmospheric gases, such as nitrogen and oxygen, dissolved in it. As the glass filled with water sits out for a few hours, its temperature rises slightly (water gets warmer),...

The Common Ion Effect
We've learned a few applications of the solubility product, so let's learn one more! This is called the common ion effect, and it can be a good way to influence the solubility of a particular ionic compound in solution, or even promote...

Practice Problem: Solubility Product Constant Calculations
We've learned that there are ionic solids that are insoluble in water, and while for the most part that's accurate, we are bending the truth a little bit. Even compounds that are totally water insoluble will still dissolve a teeny tiny...

Practice Problem: Gravimetric Analysis
What the heck is gravimetric analysis? Well let's say we want to know how much of a substance is in some mixture. We could toss it in solution and cause it to form a precipitate with some other ion in solution. We can measure the mass of...
Professor Dave Explains
Selective Precipitation
We know that insoluble compounds can form precipitates in solution when their constituent ions meet. But what if there are multiple possible precipitates? They actually may not all form at equivalent rates. We have to consult the Ksp...

Shrink a Potato with Osmosis – STEM activity
Have you ever added a spoon of sugar to your tea and wondered why it disappeared? Where did it go? The sugar did not actually disappear—it changed from its solid form into a dissolved form in a process called chemical dissolution....

Temperature and Gas Solubility
We know about solutions and solubility, but we have typically examined solid or liquid solutes dissolved in a liquid solvent. Did you know that gases can also be dissolved in liquids? Their solubilities depend heavily on temperature, so...

Recrystallization and Melting Point Analysis
Now that we have covered some important separation techniques, let's take a look at a purification technique. Sometimes a chemical reaction will produce a solid, which can precipitate from solution. But these crystals typically contain...

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...

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...
