Question

Is ink in a marker a pure substance or a mixture

Answer 1

Paper chromatography can be applied to ink to determine if it is a pure substance or a mixture of pure substances (in which two or more pure substances are combined). Since, when tested with paper chromatography, ink separates into its constituent pure substances, ink is a mixture.

Answer 2

INK IS A MIXTURE YOU CAN'T SAY IT IS A PURE BECAUSE IT HAVE NOT ONLY ONE THING OR SAY SUBSTANCE
