using mhchem in equations

[rputikar]

I am trying to follow https://github.com/quarto-ext/latex-environment#example-1 to write an equation containing chemical formula.

I can't get it working within an equation block (or inline equation) though. The \ce command works fine. Any help will be appreciated.

Is there any way to display chemical formulae (other than using mathjax/ katex and include mhchem extension) for the rendered html (i.e. render [H2SO4]{.ce})

   html: default

commands: [ce]

This will replace spans of class `ce` with the `\ce{}` command for LaTeX output, 
but leave the spans intact for HTML output. So `[H2SO4]{.ce}` becomes [H2SO4]{.ce}.

est in text: [H2SO4]{.ce} 

Test in inline equation $[H2SO4]\{.ce\}$

Test in equation

$$
[H2SO4]{.ce}
$$

Using `\ce` inline $\ce{H2SO4}$

$$
\ce{H2SO4}
$$

the output:

This works for me

Sulfuric acid formula: $\ce{H2SO4^{2-}}$

Yes it works with using '\ce' directive, however, the latex-environment extension doesn't seem to work within equation.

Math in HTML will be rendered by some library like Mathjax or KaTeX. The features from those tools need to be used.

The latex-environment extension will ignore on HTML and I don't think you want \ce to have no effect in the equation.
