to identify sodium nitrite
« on: July 31, 2009, 01:17:29 PM »
Hi,

I have an aqeous solution which I suspect contains dissolved sodium nitrite (don't know the concentration). It also contains other dissolved compounds in it which I am not sure what they are.

What tests exist to determine the presence of sodium nitrite so to indentify it? I'm not really interested in the quantity, just quality to see if its present or not.

Thanks.

To identify nitrate ion can be useful nitrite test.

To identify sodium ion you can do flame test.

However, those tests will only determine that sodium and Nitrite ions are present However, they may not be necessarily present as sodium nitrite.
Experience is something you don't get until just after you need it.

I see, thanks. Will other dissolved compounds interfere with the nitrite test?

thanks.

Philosophically, if I have K+, Na+, Cl- and Br- floating around in aqueous solution, do I have KCl, KBr, NaCl or NaBr?
