Which substance exhibits high resistance against hydrogen sulfide degradation ?
Show answer Hide answer
Answer: D. Glazed ware
Explanation
Glazed ware is chemically inert and resists hydrogen sulfide pipe degradation. Vitrified clay surfaces prevent acid attack caused by bacterial sewer gases. High chemical resistance ensures long lifespans in aggressive sewage environments. Hydrogen sulfide gas converts to sulfuric acid via bacterial action in sewers. Acid corrosion deteriorates conventional concrete and cement pipe materials. Glazing processes create impervious vitreous coatings on ceramic sewer pipes.
Sanitary sewer systems utilize glazed stoneware for corrosive industrial discharges. Municipal engineers select chemically resistant pipes for low-velocity sewer runs. Long-term durability reduces maintenance costs for underground utility networks. Reinforced cement concrete is susceptible to hydrogen sulfide acid corrosion. Asbestos cement degrades over time when exposed to aggressive sewer acids. Other listed materials lack the complete chemical inertness of glazed ceramics.
