1) Solution
2) Colloid
3) Suspension
A solution is a homogeneous mixture where the solute particles are dissolved in the solvent and the particle size is typically less than 1 nanometer (nm). A colloid is a heterogeneous mixture where the dispersed particles are larger than those in a solution but smaller than those in a suspension, typically ranging from 1 nm to 1 micrometer (µm). A suspension is a heterogeneous mixture where the dispersed particles are larger than 1 µm and can be visible to the naked eye.
