What is the identity of the unknown ink? use evidence to support your claim.

The identity of the unknown ink is based on the component of the dye coloring, which is based on the difference in the diffusion coefficient over the fixed phase

Chromatography is one technique for separating mixtures into its constituent components based on the principle of stationary and mobile phases.

Generally used to separate ink is paper chromatography. Where the stationary phase is paper and the mobile phase is solvent/sample. The ink on the pen is a mixture of several dyes. The absorbed solvent will separate the ink dye into several spots that indicate the constituent components of the dye from the ink

The separation of the ink mixture is based on the component speed.

Components that are less soluble in the mobile phase will be left behind, while those that are more soluble will move faster

When the solvent rises, the ink will also carry over, so the mixture of ink components will separate.

Paper chromatography is liquid-liquid chromatography because solvent as the mobile phase, and the fixed phase is water in a paper

Chromatography itself is part of the separation of mixtures such as centrifugation, distillation, sublimation, evaporation, or critalization

answer: the primary difference between a hypothesis and a theory is that b hypothesis is falsifiable, but a theory has been proven to be correct. theory is an explanation of something that is happening but hypothesis is a guess of something that can happen

explanation:

lol for the pointsss
