Question

What are the sources of error when performing lassaigne's test

Answer 1

Lassaigne's test or sodium fusion test, is used to make a qualitative form of analysis and understand if any halogen, nitrogen or sulfur (also referred to as foreign elements) is present when any sample is brought under heat treatment.

This is done by considering the basic property that such foreign elements are bonded on a covalent basis.

However there might be issues of errors  still.

There might be cases where cyanide ions are formed or sulfide ions are formed if reactions are undertaken with silver nitrate or other similar compounds depending upon corresponding elements and those kind of formations cause error in the test and in bringing accurate test results.

These are the main sources of error in Lassaigne's test.
