colloid
A suspension is the mixture with the largest particles.
mixture
A colloid is a mixture of solid particles suspended in a liquid.
Suspension consists of the largest particles among colloid, homogeneous mixture, solution. Suspensions contain particles that are visible to the naked eye and typically settle over time.
A suspension, such as sand and water.
heterogeneous
A colloid is a type of mixture in which medium-sized particles do not settle out on standing and scatter light. However, a suspension is a type of mixture with medium-sized particles that do settle out on standing and can scatter light.
Even if the apple juice is labelled as '100% pure', it is still a mixture of water particles, sugar particles, flavour particles, and vitamin particles. So it is a mixture, not a pure substance.
nothing, the particles are visible because the particles are in the mixture. The substances being visble and identifiable in a mixture is because that mixture is heterogenous.
Visible particles would be heterogeneous elements of a mixture. A truly homogeneous mixture would have no visible particles. However, you could still have an approximately homogeneous mixture with visible particles, evenly distributed throughout the mixture.
A heterogeneous mixture with large particles is likely to be the least stable at rest over time. This is because the large particles have a tendency to settle at the bottom due to gravity, leading to separation of the components of the mixture.
A suspension has large particles that settle out on standing.
