Chemistry Lab

A chemistry toolkit for school and university, with 16 short lessons – atoms, the periodic table, electron shells, bonding, formulas, moles, balancing, reaction types, acids and pH, titration, gases, rates, energy changes, redox, carbon chemistry and lab safety – each linked to its tool. An interactive periodic table of all 118 elements (PubChem data), a molar mass calculator with percentage composition and grams-to-moles, an equation balancer that handles brackets, hydrates and ions (written in Rust and running in your browser as WebAssembly), pH of strong and weak acids, a titration simulator with indicator colours and the pH curve, the ideal gas law, dilutions, and an element quiz.
