Classic Chemistry Experiment Illustration - Inverted Funnel Gas Collection Method #3719068 (License: Personal Use)

This black-and-white line drawing depicts a traditional chemistry laboratory method for collecting insoluble gases over water. A hand pours liquid from a beaker into an inverted funnel submerged in a water-filled cylinder, while two graduated cylinders stand ready for measurement. The illustration emphasizes procedural clarity and is typical of mid-20th-century science textbooks.

Commonly used in educational web pages, digital textbooks, or museum exhibits about historical scientific methods; matches user intent for visual explanations of gas collection techniques in chemistry curricula.
