Hydrogen chloride molecule

Hydrogen Chloride (HCl) Molecule — 3D Printable Model

A clean and accurate 3D printable model of hydrogen chloride (HCl), one of chemistry's most fundamental diatomic molecules. Perfect for students, educators, and science enthusiasts looking to bring molecular chemistry to life on the desktop.

About the Molecule

Hydrogen chloride consists of just two atoms — one hydrogen and one chlorine — joined by a single polar covalent bond. Despite its simplicity, HCl is a cornerstone molecule in chemistry, demonstrating key concepts like electronegativity, bond polarity, and dipole moments. When dissolved in water, it becomes hydrochloric acid, one of the most important strong acids in science and industry.
