Subject: Re: Susan Broshoven's (sp?) e-mail and safe electrolyte
Susan Broshoven's e-mail is sboshov@sfusd.k12.ca.us. for the information about
the lessons in Spanish.
A reasonably safe chemical for electrolyte solution is ammonium sulfate which
will make a weak acid reaction with the water. This is from ancient memory so
it needs to be checked out.......
