Sulfuric Acid 3D Molecular Model — CAS 7664-93-9

Sulfuric Acid (H2O4S, CAS 7664-93-9) — a free educational 3D molecular model for teachers and students, by MolGod.org. Element symbols are cut into each atom sphere: a self-labelled teaching aid.

Lay Sulfuric Acid on the desk and search for a ring: there isn't one. Its 7 atoms hang together through 6 bonds (4 single and 2 double). A five-minute warm-up: read the symbol on every sphere and write down the totals (2 H + 4 O + 1 S = 7 atoms). On the printed model, students can point to the sulfonic acid group (-SO3H). Worth printing alongside it: Methanesulfonic Acid (CAS 75-75-2) and dimethyl sulfone (CAS 67-71-0), structurally the nearest in the collection. For intermolecular forces: the molecule has 2 hydrogen-bond donors and 2 acceptors (computed).

MolGod.org builds and releases these models at no cost for chemistry teaching. Teachers: use it as a hands-on starter before drawing the structural formula on the board.

A ball-and-stick model of Sulfuric Acid with each element symbol recessed into its atom sphere, generated by MolGod.org from a PubChem-computed 3D conformer (not an experimental crystal structure); atomic coordinates and connectivity are unchanged. STL mesh: 103,656 triangles, closed (watertight) single solid. Coordinates in ångström (STL stores no unit) — scale the model deliberately in your slicer.

Names in other languages: Schwefelsäure (de); acide sulfurique (fr); acido solforico (it); zwavelzuur (nl); kwas siarkowy (pl); 硫酸 (zh).
