The use of Hcl, as a separation measures will react with iron atom to form (Hcl Fe = FeCl2 H2. ) in the process iron atom is lost as ion making it irreversible to get it back as an atom. The use of Benzene as a separation measures will get sulphur dissolved,since it is physical change and can be recoverable by filtering out iron atom which does not react or dissolve in benzene.while sulphur atom in solution of benzene can be recovered by evaporation to dryness (since the boiling point of benzene is 80 degree celsius. SO OPTION DDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDD IS CORRECT
The answer to the question above is surely Benzene. Sulphur (a non-polar substance) which forms a polyatomic molecule of 8.It Will only dissolve in a non-polar substance which is Benzene. After dissolution of the compound sulphur dissolves and iron is left undissolved. The filtration (a physical means of separation) is used to filter out iron as residue( undissolved part of a solution).
This is correct because sulphur dissolves in benzene to pruduce vulcanizers solution while iron does not rather can be filtered out;The alternative technique is magnetization where iron filings are captured by magnets while sulphur is left un-magnetized.
A mixture of iron and sulfur can be separated by dissolving the mixture in dilute hydrochloric acid.
The reaction between iron and sulfur with hydrochloric acid can be represented as:
Fe(s) + 2HCl(aq) → FeCl2(aq) + H2(g)
S(s) + 2HCl(aq) → H2S(g) + Cl2(g)
In this reaction, iron reacts with hydrochloric acid to form iron chloride and hydrogen gas, while sulfur reacts to form hydrogen sulfide gas and chlorine gas. Since iron chloride is soluble in water, it remains in solution, while sulfur precipitates out as a solid. This allows for the separation of the two components.
So, the correct answer is:
B. dilute hydrochloric acid
Benzene is not typically used to dissolve mixtures of iron and sulfur because it is not a suitable solvent for these substances. Benzene is a nonpolar solvent, meaning it lacks the ability to dissolve ionic or polar compounds like iron and iron compounds (such as iron sulfide). Iron sulfide is insoluble in nonpolar solvents like benzene.
Dilute hydrochloric acid, on the other hand, is capable of dissolving both iron and sulfur. Iron reacts with hydrochloric acid to form iron chloride, which is soluble in water. Sulfur, in the form of elemental sulfur or iron sulfide, can also react with hydrochloric acid to produce hydrogen sulfide gas, which can escape, leaving behind the iron chloride dissolved in the solution.
Therefore, benzene would not be effective for dissolving a mixture of iron and sulfur, while dilute hydrochloric acid is a suitable choice.
@lastborn4them Vulcanizer solution is formed by dissolving rubber in benzene not sulphur in benzene. Sulphur serves to break the double bond in rubber i.e serving as cross linkages.
the correct answer is B dilute HCL acid
FeS + 2HCL > FeCL2 + H2S
recall to sulphur and it compound
the correct answer should be Hydrochloric acid instead of benzene because, benzene is not considered a standard laboratory solvent at this level. So, the chemical separation is preferred.
Correct answer is b. Iron reacts with cl to form fecl while sulphur doesn't react with hcl atall
sulfulr is soluble in benzene while iron is not. We can't use hydrochloric acid bescuse iron will dissolve in it and not only dissolve but it will also react with it to form iron (ii) chloride, therefore, separation is not acheived..
this is a simple one . The answer should be Hcl , hcl dissolves iron but won't dissolve sulphur. to say the answer is benzene based on the fact that it dissolves Sulphur and leaves iron is quite ludicrous as sulfur is only slightly soluble in benzene. Hcl (B)
Dilute hydrochloric acid can dissolve the iron in the mixture, leaving behind the sulphur. This is because iron reacts with hydrochloric acid to form iron chloride, which is soluble in water. Sulphur, on the other hand, is not affected by hydrochloric acid and remains insoluble. Therefore, by dissolving the mixture in dilute hydrochloric acid, the iron can be separated from the sulphur.
B is crt my school change that thing
