Question

Draw a table to differentiate – True solutions, colloidal solutions & suspensions – with respect to

1. Type of mixture
2. Solute particles in the mixture.

Answer 1

True solution:

1. Homogeneous mixture.
2. Particles are extremely small less than 1 nm in diameter = 10^-9 m.

Colloidal:

1. Appears to be homogeneous actually it is heterogeneous
2. Between 1 nm and 100 nm in diameter.

Suspension:

1. Heterogeneous mixture.
2. Size larger than 100 nm in diameter. Quite large size.
