what happens when dilute sulphuric acid is added to compound of iron and sulphur
Answers
This demonstration or class experiment shows the exothermic reaction of two elements, iron and sulfur, to form the compound, iron sulfide. The two solids are mixed and heated in a test-tube (or ignition tube). The reaction can be used to illustrate elements, mixtures and compounds.
Lesson organisation
This reaction can be carried out as a demonstration or class experiment in a well-ventilated laboratory provided that the instructions provided here are strictly adhered to.
The reaction can be carried out in borosilicate glass test-tubes as a demonstration or in smaller (ignition) tubes by students. The reaction provides an opportunity to show that the properties of a compound are different from its constituent elements.
The reaction must not be carried out on tin lids in the open laboratory as is suggested in some sources. The sulfur may boil or burn releasing sulfur dioxide which is a TOXIC and CORROSIVE gas and may trigger an asthmatic attack.
from my reader hope it helps
