I wish I knew what conductivity in liquids is!

Conductivity refers to the ability of a material to let electrical current flow through it. Most people know this concept in metals and other solids. Lead and copper, for example, conduct current well. So we use copper and lead wires in small projects to conduct electricity between two elements. But what about liquids?  What makes conductivity in liquids?

For liquids, you need ions in your solution. Ions usually result when molecules break down in soluble salts, acids, and bases. We call this process dissociation, and it creates positively charged ions, called cations, and negatively charged ions, called anions.

If you have these ions in your solution, then electrons start jumping from anions to cations in an attempt to find balance again. This activity allows electrical current to flow into the solution. So the more ions the solution has the higher its conductivity. Nifty, huh? Well, there you have it guys if there are any more questions about conductivity in liquids feel free to ask!
