Which of the following is a desirable quality in a germicide?
A
It should be highly toxic to humans.
B
It should be effective against a broad range of microorganisms.
C
It should only work at extremely high temperatures.
D
It should lose its activity rapidly when exposed to air.
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 to prevent infection or contamination.
Evaluate the options based on the ideal characteristics of a germicide. It should be safe for humans, so being highly toxic to humans is undesirable.
Consider the effectiveness: a good germicide should work against a wide variety of microorganisms, including bacteria, viruses, and fungi, making broad-spectrum activity important.
Assess the conditions of use: requiring extremely high temperatures limits practical application, so this is not a desirable quality.
Stability is important: a germicide should maintain its activity during storage and use, so losing activity rapidly when exposed to air is undesirable.
