Lab Activity: Detecting Sulphur and Nitrogen in Organic Compounds

Statement 1: Kjeldahl method fails for pyridine.

Statement 2: In Kjeldahl method pyridine is easily converted to ${\mathrm{N}}_2$.

Appearance of blood red colour, on treatment of the sodium fusion extract of an organic compound with ${\mathrm{FeSO}}_4$ in presence of concentrated ${\mathrm{H}}_2{\mathrm{SO}}_4$ indicates the presence of element/s
