Schöniger oxidation

Schöniger oxidation

In chemistry, the Schöniger oxidation (also known as the Schöniger Flask Test) is a test in qualitative elemental analysis, developed by Kurt Schöniger.

:sample (with C,N,S,H,X) + oxygen (O2) + NaOH → Na+X- + Na+NO-2 + Na+2SO-3

:X = Cl, Br, F, I

It allows quantitative determination of elemental chlorine, nitrogen and sulfur in a sample.
