I use mhchem.sty ( http://www.ctan.org/tex-archive/macros/latex/contrib/mhchem/ ) to typeset chemical formulae and chemical equations.

Please try the following source code:

\documentclass{article}
\usepackage[version=3]{mhchem}
\begin{document}
\ce{Fiber - O - H + NaOH -> Fiber - O - Na + H2O}
\end{document}
