Question

The apparatus shown in the figure below was used in a series of experiments. A cotton ball soaked in either hydrochloric acid (HCl) or acetic acid (CH₃COOH) was placed at one end. Another cotton ball soaked in one of three amines (a class of nitrogen compounds)–-[CH₃NH₂, (CH₃)₂NH, or (CH₃)₃N] was placed on the other end

In one combination of acid and amine, a white ring was observed almost exactly halfway between the two ends.
Which acid and which amine were used?

Choose one or more:

HCl

CH₃COOH

CH₃NH₂

(CH₃)₂NH

(CH₃)₃N
