Chromatography is a practical technique used to separate and identify the components in a mixture. Chromatography involves a mixture being dissolved in a mobile phase (which could be a liquid or a gas) that is then passed through an immobile … Read More

Organic synthesis

So there’s no great rhyme or reason as to how best to work through organic synthesis, so in Gojimo we’ve decided to lay out some practical examples and rules to help guide you through! Without further ado let’s get stuck … Read More


First things first we’re going to look at Bronsted-Lowry theory. This was an idea brought about by two guys called Johannes Nicolaus Bronsted and Thomas Martin Lowry. According to their theory on acids and bases, a base is a compound … Read More
