Question

q6. what is the purpose of a chemical indicator in a sterilization process?
to confirm sterility
to replace biological indicators
to monitor the physical conditions of the sterilization process
to clean instruments

Explanation:

Chemical indicators in sterilization processes change color or form based on exposure to sterilization factors like heat, pressure, or chemicals. This change shows if the physical conditions (e.g., temperature, time, pressure) of the sterilization process were met. They don't confirm sterility (biological indicators do that), can't replace biological indicators (which test for actual microbial kill), and aren't for cleaning instruments (that's a different process).

Answer:

To monitor the physical conditions of the sterilization process
