Final answer:
Bleach is used as a disinfectant for kitchen sinks, toilet bowls, and to remove stains from clothes, which is a true statement. It has bactericidal properties and is used for disinfecting various surfaces, but it can also damage certain materials and harm health if not used properly.
Step-by-step explanation:
Bleach can indeed be used as a disinfectant for kitchen sinks, toilet bowls, and to remove stains from clothes. This is true because many bleaches, particularly those containing sodium hypochlorite, have broad spectrum bactericidal properties. They are useful for disinfecting and sterilizing various surfaces and also play a role in swimming pool sanitation to control bacteria, viruses, and algae. Bleaches are also commonly used in industrial processes like the bleaching of wood pulp and have other uses such as removing mildew, killing weeds, and increasing the longevity of cut flowers.
It should also be noted that while bleaches are effective for these purposes, they can react with many organic substances and may weaken or damage natural materials like fibers, cloth, and leather. Care should always be taken to use bleach safely, avoiding ingestion, inhaling fumes, or contact with skin or eyes to prevent health damage.
In comparison to other chemicals, the effectiveness of chemical disinfectants like bleach has historically been compared to phenol according to item 15 provided. For microbial control on tissues to prevent infection, an antiseptic is typically suitable, as indicated by option B in item 2 provided.
