Precipitation Reactions - An Introduction

Today, we were introduced to a special type of reaction called precipitation. This is where you combine two solutions, and a solid (precipitate) is formed. The example we looked at was adding Iron (III) Nitrate to Sodium Hydroxide. A brown precipitate formed; this was called Iron (III) Hydroxide:

Then, we were given a solution and added Sodium Hydroxide to that. We had to create a diagram like the one below to show what happened:

Here is a video of some of these concepts being taught to another class:
