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...

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...

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...

Upon viewing the Solutions at Work video series, students will be able to do the following: Explain that a solution is a type of mixture made of two or more substances that are evenly distributed. Provide an example of a common solution....

In this video, we explore the concept of solubility and how different substances dissolve in water. We learn that solubility refers to the amount of solute that can be dissolved in a solvent, and that a saturated solution holds the...

In this video, the concept of solubility is explained, including factors that affect solubility and how to interpret solubility curves. The video also discusses how temperature, pressure, and pH can affect solubility, as well as how...

Why do some things dissolve in water while others don't? Is a supersaturated solution just a beaker with a cape? All this and more!

What are electrolytes? Yes, they're what plants crave. But they are also ionic solids dissociated in solution, such that they can conduct electrical current. Learn about solutions!

Upon viewing the Solutions at Work video series, students will be able to do the following: Explain that a solution is a type of mixture made of two or more substances that are evenly distributed. Provide an example of a common solution....

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...

Water can dissolve more substances than anything else on earth...so why doesn't it dissolve everything away?

Cookie the chef is a multitalented guy. He’s an amazing barista, too! He really takes filter coffee to the next level. Meanwhile, First Mate Phil needs a hand, or a hook, with fixing the ship’s hull. This lesson will explore separation...

This lesson will see us finishing work on our medieval torture device. We will be texturing the racks, and this will include blood decals as well.

To make a solution of something by mixing a soluble substance into a solvent, such as salt into water.

Separation techniques are important in chemistry, and they won't always be as easy as filtration. Sometimes we need to separate two compounds that are dissolved in the same solution. Often we can take advantage of a difference in...

The video explains how to separate mixtures through physical processes without breaking any chemical bonds. The speaker describes various techniques such as filtration, crystallization, chromatography, and distillation, while explaining...

The video is about the various techniques used to separate different components of a mixture. The presenter discusses the differences between mixtures and compounds, and how mixtures are not chemically combined, but rather just mixed. He...

Now that we have covered a variety of separation techniques, we know how to get an isolated product! But if it's a solid, it may contain impurities. Recrystallization is a common organic chemistry laboratory technique for the...

Today im demonstrating the Synthesis of Benzocaine! <br/>
I used<br/> 150<br/>ml EtOH
15gm PABA
6ml Sulfuric acid

It explains separation of solid-solid mixture by using two methods, namely sublimation and evaporation.
