Color changes make for a lot of fun in the chemistry lab. But what is this that we synthesized, that turned from near-black to emerald to pea-green? It wasn’t what we expected! Does that mean the experiment didn’t work?
Chemistry ALWAYS works! We just don’t always understand what happened. The research chemist takes on the challenge of considering what was observed and exploring what might have caused those results…and then trying the process all over again!
