LaTeX for Chemistry: Writing Chemical Equations and Formulas

Writing chemistry in LaTeX requires combining math mode with specialized packages. This guide covers the essential techniques.

Chemical Formulas

Simple formulas use subscripts: H_2O, CO_2, Na_2SO_4. For more complex formulas: (NH_4)_2SO_4.

Chemical Equations

Use \rightarrow for reaction arrows: 2H_2 + O_2 \rightarrow 2H_2O. For equilibrium: \rightleftharpoons.

Reaction Conditions

Use \xrightarrow[]{heat} or \xrightarrow[]{catalyst} for conditions above the arrow. Use \xrightarrow[\text{pressure}]{\text{temperature}} for conditions above and below.

Isotopes and Charges

Isotopes: ^{235}_{92}U. Charges: Na^+, SO_4^{2-}. Ions: H_3O^+.
