Match the chemical compounds listed in List I with their corresponding primary daily life … — State PSC Exam

Match the chemical compounds listed in List I with their corresponding primary daily life or industrial applications in List II:

Silver Iodide ( $AgI$ )Cloud seeding for artificial rain synthesis
Sodium Benzoate ( $C_6H_5COONa$ )Preservative for acidic foods and carbonated beverages
Calcium Phosphide ( $Ca_3P_2$ )Generation of phosphine gas for Holme's marine signals
Aluminium Sulfate ( $Al_2(SO_4)_3$ )Coagulant for municipal water clarification

Cevap

Silver Iodide matches with cloud seeding for artificial rain synthesis; Sodium Benzoate matches with preservative for acidic foods and carbonated beverages; Calcium Phosphide matches with generation of phosphine gas for Holme's marine signals; Aluminium Sulfate matches with coagulant for municipal water clarification.

Each chemical compound is accurately linked to its specific daily life or industrial application: Silver Iodide is used for cloud seeding, Sodium Benzoate serves as an acidic food preservative, Calcium Phosphide generates phosphine gas for marine signaling, and Aluminium Sulfate functions as a water coagulant.

Adım Adım Çözüm

Identify the industrial function of Silver Iodide

Silver iodide (

AgI

) is applied in weather modification via cloud seeding due to its ice-like crystallographic symmetry.

Matching chemical agents to atmospheric weather intervention processes.

Identify the household/food application of Sodium Benzoate

Sodium benzoate (

C_6H_5COONa

) acts as a chemical preservative inhibiting microbial growth in acidic consumables.

Matching organic salts to food chemistry and preservation techniques.

Identify the maritime safety application of Calcium Phosphide

Calcium phosphide (

Ca_3P_2

) hydrolyzes in seawater to liberate spontaneously combustible phosphine gas (

PH_3

) used in Holme's signals.

Matching inorganic phosphides to spontaneous combustion signaling reactions.

Identify the water treatment role of Aluminium Sulfate

Aluminium sulfate (

Al_2(SO_4)_3

) neutralizes negative charges on suspended colloids, promoting flocculation and clarification in water purification plants.

Matching metal salts to industrial coagulation and sanitation processes.
