Acid Base Solutions

 Yesterday we started a new unit over a different type of solution, acid base. I learned that there are three different models for acid base solutions but we will only learn about two. The first one I knew, it was called Arrhenius acids and bases. Acids have a leading (H+) ion and bases have a (OH-) ion.

The new one I learned was called Bronsted-Lowery Acids and Bases, where during the solution a (H+) ion leaves the acid and goes and is put into the base. These solutions often in equilibrium, so they can occur both ways.

The reason the pairing are attached to "conjugate acid/base" means that when the equation is read the other way (right to left) that they are the acid and base. 

Confuses? Look here for some more info.
