Advertisement Advertisement Spotlight Advertisement WebFAQs about Chloroform. Q.1: What is the nature of chloroform- acid or base? Answer: The colour is compared to the 2 mL blank of distilled water having a pH range in 5.0 – 7.0. If the sample solution is discoloured i.e. yellow relative to the blank i.e. blue-green, the deuterated chloroform is acidic.
