A student, by mistake, mixed sulphur powder with iron filings. The correct techniques were suggested to separate the sulphur from the mixture is dissolving in carbon disulphide, filtration, evaporation.

Explanation:

Mixed solution of sulphur powder and iron filings is mixture of two compounds results in the reaction. As we need to extract the sulphur from the mixed solution by following techniques:

(1). Sulphur will dissolve in carbon disulphide, So by dissolving it in the carbon disulphide can give us the sulphur.

(2). As Iron has magnetic properties so it settles down as a residue when filtration is done.

(3). Evaporation of filtrate will results in getting sulphur back.

The correct answer is option A). dissolving in carbon disulphide, filtration, evaporation
