Identify The Chemical Part 2 Quiz

Identify The Chemical Part 2 Quiz opens with a familiar scientific moment where a simple colour change reveals hidden information. A clear liquid meets a strip of litmus, and blue litmus turns red, quietly signalling an acid base interaction without any sound or spectacle. This kind of observation has guided chemistry for centuries, relying on patience rather than equipment. The quiz follows this tradition by focusing on visible clues that make substances easier to recognize. A small piece of trivia is that litmus dye comes from lichens, organisms once gathered by hand and processed carefully to create natural indicators. Long before modern chemicals existed, these dyes helped people understand chemical behaviour using nothing more than colour and careful watching.
