Solid-liquid mixing coating colors

In popular media, you may see a chemist in a lab coat, surrounded by glassware, mixing colored solutions that froth and give off billowing fumes. Most reactions in solution are not this dramatic, and good technique requires safer mixing procedures however, it is true that aqueous solution chemistry is central to laboratory chemistry. And many environmental reactions and almost all biochemical reactions occur in solution. Liquid solutions are easier to store than gases and easier to mix than solids, and the amounts of substances in solution can be measured precisely.
