Question

What type of mixture scatters light and cannot be filtered easily?
a colloid, a heterogeneous mixture
a solution, a heterogeneous mixture
a colloid, a homogeneous mixture
a solution, a homogeneous mixture

Answer 1

Answer: The correct answer is a colloid, a homogeneous mixture.

Explanation:

Colloid is a type of solution in which particle size is more than true solutions ans less than suspension. The particles are thoroughly dispersed in the medium and can scatter light which falls on it. This property of scattering of light is known as Tyndall effect.

In a solution, particle sizes are very small and cannot be seen clearly with bare eyes. These solutions do not show the property of Tyndall effect.

Homogeneous mixtures are defined as the mixtures which have the same appearance and composition throughout the substance. The particles are not physically distinct in these mixtures. In these, the particles cannot be separated by the process of filtration.

Heterogeneous mixtures are defined as the mixtures which does not have the same appearance and composition throughout the substance. The particles are physically distinct in these mixtures. The particles differ in the sizes. In these, the particles can be separated by the process of filtration.

Hence, the correct answer is a colloid, a homogeneous mixture.
