ink is true solution or colloid or suspension??
some say true solution because its only powder and water.
some say colloid.
is it suspension because we can see so many colors when we do chromatography
It is a colloid. In colloid the solute doesn't completely dissolve. It can be seen.
Though in colloidal solution you actually can't see the particles settling down. They are not dissolved completely, due to which the the solution also shows tyndall effect.
