Question

Name the compound formed by heating iron filling with sulphur powder. What will happen if we add carbon tera chloride to this compound?

Answer 1

Dear student,

i)When a mixture of iron and S is heated it forms iron sulphide

$Fe+S\stackrel{∆}{\to }$ FeS
$FeS+2HCl\to FeC{l}_2+$$H_{2}S$

ii) The carbon tetrachloride undergoes reductive dechlorination in the presence of ions of (Fe2+) and sulphide ions (S2-) freshly precipitated ferrous sulfide (FeS) as reducing agents,
