Solutions
In this video Paul Andersen explains the important properties of solutions. A solution can be either a solid, liquid or gas but it must be homogeneous in nature. The solutes can not be separated with a filter and so either chromatography...

What Happens When You Get Electrocuted?
Most of the cases we call “electrocutions” are actually electric shocks: an electric current running through a body. Whether an electric shock becomes an electrocution depends on the nature of the current involved.

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...
