Chemistry

Chemists do make use of \LaTeX but they have different typesetting conventions from mathematicians. For example the chemical \cf{H2O} is quite different from the mathematical H_2O . Martin Hensel’s mhchem package allows the easy typing of chemical symbols. Here are some examples taken from mhchem’s documentation. Needless to say, not being a chemist, they don’t mean much to me :smile:

Hover over, or click on a formula, to see the underlying latex code.

\cf{(NH4)2S}

\cf{^{227}_{90}Th+}

\cf{Fe`{III}[Fe`{III}Fe`{II}(CN)6]3}

\cf{2H+,{(aq)}}

\cf{[Cd\{SC(NH2)2\}2].[Cr(SCN)4(NH3)2]2}

\ce{SO4^2- + Ba^2+ -> BaSO4 v}

\ce{Zn^2+
<=>[\ce{+ 2OH-}][\ce{+ 2H+}]
{\underset{\text{amphoteres Hydroxid}}{\ce{Zn(OH)2 v}}} %group!
<=>[\ce{+ 2OH-}][\ce{+ 2H+}]
{\underset{\text{Hydroxozikat}}{\cf{[Zn(OH)4]^2-}}}% group!
}

\ce{{{x\,}} Na(NH4)HPO4 ->[\Delta]
(NaPO3)_{{x}} + {{x\,}} NH3 ^ + {{x\,}} H2O}

  3. But, how do I install the mhchem on my wordpress blog? Are there some instructions for newbies somwhere?

  4. mhchem is included with most TeX distributions so all you need to do is add the package to the compilation. In class.latexrender.php after the line
    $string .= "\usepackage{amssymb}\n";
    add the line
    $string .= "\usepackage{mhchem}\n";
