For my chemistry course, our lab-leader insists that we use roman numerals for the numbering of reaction equations, and arabic numerals for the numbering of mathematical equations. So when I write
\begin{equation}
some reaction equation
\end{equation}
I would like LaTeX to use roman numerals to number the equation, and I would like them to follow a counter different from the counter for the arabic numerals. Can I customize it in this way, or if it's difficult, how could I do it manually?
Also, I would like the mathematical equations to be numbered, for instance,(1-1)
instead of (1)
when it's the first mathematical equation of section 1. How can I do that?

In the following example I use the reaction environment as given by Martin H. to question 11456 and I changed to Roman the numbering.
