Salts are formed due to neutralisation reactions between acids and bases, due to which a neutral ph compound called a salt is formed, for eg: naoh(base) reacts with hcl (acid) to form nacl salt and water.

a solution is always transparent, light passes through with no scattering from solute particles which are molecule in size. the solution is homogeneous and does not settle out. a colloid is intermediate between asolution and a suspension. while asuspension will separate out a colloid will not.
