Which of the following is a desirable quality in a germicide?
A
It should have a strong, persistent odor.
B
It should be inactivated by organic matter.
C
It should be corrosive to surfaces.
D
It should be effective at low concentrations.
Verified step by step guidance1
Understand the purpose of a germicide: it is a chemical agent used to kill or inhibit the growth of harmful microorganisms on surfaces or in environments.
Evaluate each option based on the ideal characteristics of a germicide. For example, a strong, persistent odor is generally undesirable because it can be unpleasant and potentially harmful to humans.
Consider the effect of organic matter on germicides. A good germicide should not be easily inactivated by organic matter, as many environments contain organic materials that could reduce its effectiveness.
Assess corrosiveness: a germicide should not be corrosive to surfaces because this would damage equipment or materials where it is applied.
Recognize that an effective germicide should work at low concentrations to minimize toxicity, cost, and environmental impact while still effectively killing microorganisms.
