Answer:

C. Suspensions lose their consistency while colloids remain

consistent.

Explanation:

What is Suspension?

Simply defined as a heterogeneous mixture of two substances in which one is dispersed into the other, suspensions involve particles larger than those found in solutions. The bigger particles of a suspension usually settle or separate out of a mixture upon standing or are able to be filtered out, although not through filter paper. Gravity is able to pull the visible particles in a suspension down if undisturbed, and they will stay that way unless being actively mixed.

What is Colloid?

They do not separate upon standing and cannot be separated by filtration. The particles in a colloid land in size between those in a solution and a suspension and may be solid, liquid, or gas. The two parts in every colloid mixture are its particles and the dispersing medium, and the particles are spread evenly in the medium, which can also be solid, liquid, or gas.

What is the difference between suspensions and colloids?

• Particles in a suspension are usually more than 1,000 nm, while those in a colloid range from 1-1,000 nm.

• Unlike those in a suspension, particles in a colloid do not separate when sitting still.

• The particles in a suspension may be separated by filtration unlike those in a colloid.

• Colloids are able to scatter light, but suspensions cannot transmit light.

• Particles in a suspension can be seen by the naked eye, but those in a colloid must be viewed using a light microscope.
