Which of the following separation techniques would show that black ink is a mixture of chemical compounds?
Answer Details
Chromatography would show that black ink is a mixture of chemical compounds. Chromatography is a separation technique that separates different components of a mixture based on their ability to move through a medium, such as paper or a column, at different rates. Since black ink is not a pure substance, but rather a mixture of different chemical compounds, chromatography would be able to separate the different compounds and show that they are present in the ink. By comparing the separation patterns of the black ink to those of known compounds, the different components of the ink can be identified.
