I want oxidation/reduction arrows, overhead and below, with oxidation numbers also.
Like the one featured in the watermark background on this very page upper left corner.
Unfortunately, chemexec disrupts mhchem and thwarts its smart auto-formatting so you have to manually set superscripts and subscripts - very annoying. So if you can find a less disruptive way of implementing the oxidation state number above the species while you're at it, please do!
\documentclass[a4paper,12pt]{article}
\usepackage[version=3]{mhchem}
\usepackage{chemexec}
\begin{document}
\ce{2 \ox{0}{Na} + \ox{0}{Cl}_2 -> 2 \ox{+1}{Na}^+ + 2 \ox{-1}{Cl}^-}
\end{document}
texdoc mhchem
doesn't contain a single hit for "oxidation"... – Seamus May 13 '11 at 13:25mhchem
's\ce
command. You can have\ce
inside tikz nodes so you could let tikz handle the arrows too, but that's suboptimal... – Seamus May 13 '11 at 14:09
