Statement I : Nitrogen present in organic compound is first converted to ammonium sulphate in kjeldhal’s method.
Statement II : Lassaigne’s extract containing thiourea gives blood red colour on addition of $FeC{l}_3$solution.

(i) Nitrogen present in organic compound is first converted to ammonium sulphate in Kjeldahl’s
method.
(ii) In Lassaigne entract of containing thiourea gives blood red coloration on addition of ${\mathrm{FeCl}}_3$  solution due to  ${\left[\mathrm{Fe}{\left({\mathrm{H}}_2\mathrm{O}\right)}_5\mathrm{SCN}\right]}^{2+}$  complex formation.
