Answer 2

The correct answer is option (1) By shaking and watching for separation.

• A colloid and suspension are often distinguished by shaking each of the mixtures and so keeping them undisturbed to watch if their elements separate. The particles of a suspension area unit larger in size and settle to very cheap when whereas|it slow|your time} while the particles during a mixture area unit comparatively stable and don't settle simply.
• For example, milk could be a mixture and a combination of sand and water could be a suspension. If they're unbroken and undisturbed for a few times, sand settles to very cheap whereas the elements of milk don't settle.
