Which one of the following pairs is correctly matched?a)Silver Iodide ...
Correct Match: Zinc Phosphide - Rat Poison
Zinc phosphide is a chemical compound primarily used as a rodenticide. Here's a detailed explanation of why option 'C' is the correct match:
What is Zinc Phosphide?
- Chemical Composition: Zinc phosphide (Zn3P2) is a grayish-black powder.
- Usage: It is commonly used to control rodent populations, particularly in agricultural settings.
Mechanism of Action
- Toxicity: When ingested, zinc phosphide reacts with moisture in the stomach to release phosphine gas, which is highly toxic.
- Effects on Rodents: This gas interferes with cellular respiration, leading to respiratory failure and death.
Comparison with Other Options
- Silver Iodide - Horn Silver: Silver iodide (AgI) is not known as horn silver; horn silver refers to a mineral containing silver chloride, not iodide.
- Silver Chloride - Artificial Rain: Silver chloride (AgCl) is used in photography and does not have a direct relationship with artificial rain.
- Zinc Sulfide - Philosopher’s Wool: Zinc sulfide (ZnS) is not referred to as philosopher's wool; that term traditionally refers to a form of tin oxide.
Conclusion
The only accurate pairing among the options provided is "Zinc Phosphide - Rat Poison," as it clearly outlines the use of zinc phosphide in pest control, making option 'C' the correct answer.

Under natural stages this tension remains tolerable because of the limited size of the social groupings. If, however, in the artificial environment of captivity, the group size becomes too big, or the space available too small, then the status ‘rat race’ soon gets out of hand, dominance battles rage uncontrollably and the leaders of the packs, prides, colonies or tribes come under (126) strain.
