You know how in movies, and TV shows, and commercials, and in pamphlets, etc. chemistry is always depicted as smiling scientists in lab coats, gloves, and goggles, holding beakers and Erlenmeyers of colored solutions? Something like this:
Chemistry is rarely ever like that… More often it’s pouring colorless solutions into more colorless solutions, and hoping something you can’t see actually happens. But today I got to do colorful chemistry! In Chem 3020 we just wrapped up a lab that involved using various pH indicator solutions. Colorful pH indicator solutions! Here is a photo of the beaker that I used to collect my waste solutions:
Isn’t it pretty? I actually didn’t intend for this to happen, and if I mixed it all, it’d probably turn into a dark greenish-grey mess. But I dumped out all the red solutions first, then the orange ones, and finally the green/blue ones. So… accidental rainbow!
