Final answer:
The true statement is that chlorine bleach (d) is an effective disinfectant; however, it must be used with caution as it is corrosive and can produce toxic fumes if mixed with certain substances.
Step-by-step explanation:
The true statement about chlorine bleach is that it is an effective disinfectant. Chlorine and its compounds, such as sodium hypochlorite—the chemical component of common household bleach—are widely used to disinfect and sterilize various surfaces and to control microorganisms in swimming pools and drinking water. Chlorine is valued for its oxidative properties that can destroy a wide range of pathogens.
However, chlorine bleach is not safe to use with all plastics as it can be corrosive. It must be handled with care, particularly because mixing it with other cleaning agents like ammonia or acids can produce toxic fumes. While it is used in salons, spas, and barber shops, proper safety protocols should be followed to ensure both worker and client safety.
