A free, no-account workbench for chemistry calculations and first-pass FTIR peak lookup, with worked steps and explicit limits.

Landing page captured for the 2026-11-01 issue.

For: First-year chemistry learners and FTIR users
Worth noticing: Molarity inputs are calculated locally in the browser; the FTIR tool warns that overlapping indicative ranges are not validated for identification or forensic reporting.

Field notes

The molarity workflow asks for solute mass, molar mass, and final solution volume, then says it will show the formula, substitutions, intermediate result, and assumptions. For FTIR, users can enter several peak positions and choose a ±5 or ±10 cm⁻¹ tolerance. The page says calculator inputs stay in the browser and cautions that the lookup is not validated for identification or forensic reporting; several additional modules remain on the roadmap.
