Colorful Chemistry Experiment with Test Tubes | Science Education Visual #286204 (License: Personal Use)

This illustration depicts a standard laboratory rack holding six glass test tubes, each filled with a distinctively colored liquid: purple, yellow, cyan, green, pink, and transparent. Bubbles are visible in the purple, cyan, and pink tubes, suggesting ongoing gas-producing chemical reactions. The clean, schematic style makes it ideal for educational materials explaining basic chemistry concepts like acid-base reactions or gas evolution.

Used in science education websites, classroom presentations, or STEM resource pages to visually represent chemical experiments, lab safety, or reaction observation. Matches user intent for learning or teaching introductory chemistry.
