    What is a suspension?

    A heterogeneous mixture where undissolved particles are large enough to be seen with the naked eye.

    What size are particles in a suspension?

    Particles in a suspension are larger than 10^-5 cm in diameter.

    What happens to particles in a suspension?

    In a suspension, particles remain undissolved, forming a heterogeneous mixture. These particles settle over time.

    How does a solution differ from a suspension?

    A solution is a homogeneous mixture where the solute particles dissolve uniformly throughout the mixture.
