I have been asked for Eriochrome Black T indicator and EDTA for water testing. And nitrate/nitrate ions tests. This is for a student doing chemistry by Distance Ed. She doesn't have any more information. Can anyone help? This is for tomorrow.
Thanks
Carol

So, heaps of notice, then!
We use indicator sticks for water testing these days; they're easy to use and accurate enough....from SBS.
