# mhchem extension
|
|
|
|
This extension adds to KaTeX the `\ce` and `\pu` functions from the [mhchem](https://mhchem.github.io/MathJax-mhchem/) package.
|
|
|
|
### Usage
|
|
|
|
This extension isn't part of core KaTeX, so the script should be separately included. Write the following line into the HTML page's `<head>`. Place it *after* the line that calls `katex.js`, and if you make use of the [auto-render](https://katex.org/docs/autorender.html) extension, place it *before* the line that calls `auto-render.js`.
|
|
|
|
```html
|
|
<script defer src="https://cdn.jsdelivr.net/npm/katex@0.16.2/dist/contrib/mhchem.min.js" integrity="sha384-RTN08a0AXIioPBcVosEqPUfKK+rPp+h1x/izR7xMkdMyuwkcZCWdxO+RSwIFtJXN" crossorigin="anonymous"></script>
|
|
```
|
|
|
|
If you remove the `defer` attribute from this tag, then you must also remove the `defer` attribute from the `<script src="https://../katex.min.js">` tag.
|
|
|
|
### Syntax
|
|
|
|
See the [mhchem Manual](https://mhchem.github.io/MathJax-mhchem/) for a full explanation of the input syntax, with working examples. The manual also includes a demonstration box.
|
|
|
|
Note that old versions of `mhchem.sty` used `\cf` for chemical formula and `\ce` for chemical equations, but `\cf` has been deprecated in place of `\ce`. This extension supports only `\ce`. You can define a macro mapping `\cf` to `\ce` if needed.
|
|
|
|
### Browser Support
|
|
|
|
This extension has been tested on Chrome, Firefox, Opera, and Edge.
