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.
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.
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 suspension has large particles that settle out on standing.
