Question

Give a detailed explanation of the separation of black ink by CHROMATOGRAPHY TECHNIQUE.

Answer 1

Answer:

To perform ink chromatography, you put a small dot of ink to be separated at one end of a strip of filter paper. This end of the paper strip is placed in a solvent. The solvent moves up the paper strip and, as it travels upward, it dissolves the mixture of chemicals and pulls them up the paper.

brilliant pls

thanku✌️.......

Answer 2

Answer:

chromatography is a technique that works on the principal of different solubility levels of components of a substance. the substance with greater solubility dissolves faster and thus gets separated first following by the others.

To perform it with black ink

1. put a dot of black ink about 5cm from the bottom end of a filter paper.
2. tie this paper to a stick and emmerse bottom end of the filter paper in a beaker with a solvent (water),placing the stick on the rim of the beaker horizontally to set the paper such that the ink spot is just touching the solvent (water)
3. as the water rises up it will take the components of ink with it and dissolve different colours at different levels due to which they will be shown as rising colours.

I hope it helps☺️

pls mark it as the brainliest if it does
