1 chlorine gas 2 hypochlorites 3 iodophors
match each of the options above to the items below.
large scale disinfection of drinking water

skin and tissue antisepsis

Explanation:

• Chlorine gas is commonly used for large - scale disinfection of drinking water due to its effectiveness and relatively low cost for treating large volumes.
• Hypochlorites (such as sodium hypochlorite) are widely used in restaurants (for cleaning utensils), hospitals (for surface disinfection), homes (general cleaning), and pools/spas (to kill microorganisms in water).
• Iodophors are used for skin and tissue antisepsis as they release iodine slowly, providing a germ - killing effect without excessive tissue damage.

Answer:

1. Chlorine gas - Large scale disinfection of drinking water
2. Hypochlorites - Disinfection in restaurants, hospitals, homes, and pools/spas
3. Iodophors - Skin and tissue antisepsis
