In the DCPIP test, if vitamin C is absent, what color is observed?

Explanation:
DCPIP is an indicator used to detect reducing agents like vitamin C. Its oxidized form is blue, and when it is reduced by vitamin C it becomes colorless. If vitamin C is absent, there is nothing to donate electrons to DCPIP, so it stays in its blue oxidized form. Therefore, the color observed is blue.
