Question

a 10% solution of one part household bleach to nine parts water gives a strong enough solution to decontaminate most surfaces, tools, and equipment effectively if left for 10 min. True or False

Answer 1

A 10% solution of household bleach to water is strong enough to decontaminate most surfaces, tools, and equipment effectively if left for 10 minutes.

Step-by-step explanation:

The statement is true. A 10% solution of one part household bleach to nine parts water is strong enough to decontaminate most surfaces, tools, and equipment effectively if left for 10 minutes. This is because bleach, which contains sodium hypochlorite as its active ingredient, acts as a disinfectant by releasing chlorine, which is an effective antimicrobial agent. The solution works by breaking down the proteins in microorganisms, effectively killing them and preventing their growth. Therefore, using a 10% bleach solution for disinfection is a recommended practice.
