Question

Is ink a homogenous or a heterogeneous mixture? Explain briefly.

Answer 1

I​nk is a colloidal solution.The components of ink can be separated by evaporation because ink is a mixture of dye (non-volatile component ) and water (volatile component). Also, a colloidal solution is a heterogeneous mixture in which the solute particles of around 1-100 nm in size are disperesed in the solvent. So, ink can be called as a heterogeneous mixture.
