B:
C:
D:
Correct Answer
C
Explanation
The use of alkaline pyrogallol in an experiment typically indicates that the experiment involves the absorption of oxygen from a closed system. Alkaline pyrogallol is commonly used in experiments to absorb oxygen because it reacts with oxygen to form a brown precipitate of insoluble polymeric products. This property makes it useful in experiments where the removal of oxygen is necessary, such as in determining the oxygen content of gases or in experiments involving anaerobic conditions. Therefore, the experiment connected with the use of alkaline pyrogallol likely involves studying oxygen consumption or removal from a system.
