Overview

Sulfur is the natural element mineral sulfur of the sulfur family. It is obtained by mining, heating and melting, and removing impurities; or it is processed from sulfur-containing minerals.

Description

Sulfur is irregular in shape and is yellow or slightly greenish-yellow. The surface is uneven and has a greasy luster, often with many small holes. When held tightly in the hand and placed next to the ear, a slight cracking sound can be heard. It is light in weight, loose in texture, and fragile, and the fracture surface is often needle-shaped crystals. It has a distinctive odor and a mild taste.

Identification

When sulfur burns, it melts easily, the flame is blue, and there is a pungent odor of sulfur dioxide.

Assay

Weigh accurately about 0.2 g of the powder, place it in a conical flask, accurately add 50 ml of 0.5 mol/L ethanol potassium hydroxide titration solution, add 10 ml of water, heat in a water bath to dissolve, and evaporate the ethanol (until there are no bubbles and no alcoholic odor). Add 40 ml of water, insert a small funnel into the neck of the bottle, boil gently for 10 minutes, cool, carefully add 5 ml of hydrogen peroxide test solution , shake well, heat in a boiling water bath for 10 minutes, cool to room temperature, rinse the funnel and the inner wall of the bottle with water, add 2 drops of methyl orange indicator solution, titrate with hydrochloric acid titration solution (0.5 mol/L), and correct the titration result with a blank test. Each 1 ml of ethanol potassium hydroxide titration solution (0.5 mol/L) is equivalent to 8.015 mg of sulfur (S).

The content of sulfur (S) in this product shall not be less than 98.5%.
