Interpretation Introduction

(a)

Interpretation:

The product shown in the image (a) should be classified into solution, colloid or heterogeneous mixture.

Concept introduction:

The solution is defined as usually a homogenous mixture of two liquids whose particle size is less than 1 nm.

The colloids are the class of mixtures that have particles size much greater than the solutions. They can be clearly distinguished because of the presence of particles that constitute the dispersed phase of the colloidal systems and render them opaque. Butter milk is an example of colloids. There are various subcategories of colloids such as sol, foam, aerosol, emulsions. The particle size of colloids lies in the range of 109107 m.

The heterogeneous mixtures are essentially those mixtures that have non-uniform composition. The average particle size of heterogeneous mixture or suspension is more than 1 μm .The suspension is subclass of heterogeneous mixture whose particles are large and do not dissolve into the solvent to give a uniform composition.

Interpretation Introduction

(b)

Interpretation:

The image (b) should be classified into either solution colloid or suspension on the basis of its appearance.
