A sample of orange juice is suspected to have been contaminated with a yellow dye. Which of the following methods can be used to detect the dye?
Answer Details
Chromatography can be used to detect the yellow dye in the sample of orange juice suspected to be contaminated. Chromatography is a technique used to separate mixtures of substances into their individual components. It works by passing a mixture through a stationary phase, which is typically a solid or a liquid supported on a solid, and a mobile phase, which is typically a liquid or a gas. The components in the mixture separate out based on their interactions with the stationary and mobile phases, and can be identified by their distinct positions on the stationary phase.
In this case, the orange juice sample suspected to be contaminated with the yellow dye can be passed through a chromatographic column, and the dye can be separated from the other components in the sample based on its interactions with the stationary and mobile phases. Once the dye is separated, it can be identified by its characteristic position on the stationary phase or by using other analytical techniques.
Therefore, the correct answer is "Chromatography".
