Chemical Chameleon

Introduction

The Chemical Chameleon is a very interesting and beautiful demo to perform. You start with a purple solution and a colorless one. Once you add them together, you get green then yellow. Not as striking as oscillation reactions (in my opinion) but still a very beautiful demo.

How to: Water Flow in Condensers

Introduction

Many reactions require the use of a condenser. Any fluid-cooled condenser needs, obviously, a liquid coolant. The most common one is cold water.

What I want to address here is: how to create a flow of said coolant inside the condenser? Surprisingly, the most common and accepted way of doing so is by conecting the condenser to a water tap, open said tap and let the water flow. In my opinion, this method isĀ  straightforward bad.

Benzoic Acid from the Oxidation of Toluene

Introduction

In this experiment I’ll be making Benzoic Acid from the oxidation of Toluene. Before starting, let me remind you that it is much easier and cheaper to simply buy Benzoic Acid or obtain it using other methods. This procedure was done to simply explore the chemistry behind it. However, it might be a good source of Benzoic Acid if you can’t find it anywhere.
