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

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