Скачать или смотреть I Extracted Cobalt Metal from Red Bull’s B12 (Here’s What Happened)

In this video we find a very unlikely connection between Red Bull and cobalt metal. As most know by now, Red Bull obtains most of its energetic feeling through its caffeine and sugar; however, hiding deep inside in its Vitamin B12 form, methylcobalamin lies an atom of cobalt.
Join me as we explore how to extract cobalt from Red Bull by breaking down the Vitamin B12 molecule and transforming the cobalt ions into pure metallic cobalt. We are going to walk through a process, step by step, including the chemical digestion of B12 with aqua regia, precipitation of cobalt, and a thermite reaction that reduces the cobalt oxide to its metallic form.
During this video, you will learn the following:
In this video, you will learn:
How Red Bull’s Vitamin B12 contains cobalt at its center
The scientific principles behind extracting cobalt from a small amount of B12
A detailed, step-by-step breakdown of the chemical reactions involved
How powerful reactions, such as thermite, can be used to reduce cobalt oxide to metal
