Kjeldahl’s method depends upon the fact that most of the organic compounds containing nitrogen are quantitatively decomposed to give$(\mathrm{N}{\mathrm{H}}_4{)}_2\mathrm{S}{\mathrm{O}}_4$when heated strongly with conc.${\mathrm{H}}_2\mathrm{S}{\mathrm{O}}_4$. In this method$\mathrm{C}\mathrm{u}\mathrm{S}{\mathrm{O}}_4$acts as catalytic agent.
