Question

What kind of solution is milk opt a suspencian opt b colloid opt c true solution opt d alloy​

Answer 1

Answer:

Hint: We know that mixtures are of two types, homogeneous mixture and heterogeneous mixture. A mixture which possesses a uniform composition all over the solution is called homogeneous mixture, whereas a mixture which possesses a non-uniform composition is called non-homogeneous mixture. Milk comes under the category of non-homogeneous mixture.

Complete step by step answer:

We know that, when the components of the homogeneous mixture are all in the same phase, it is known as the solution. The solution contains a solute component and a solvent component. On the other hand, suspension acts as a heterogeneous mixture. In suspension, the particles of solute would not dissolve and remain in the suspension.

In case of colloid, the particles spread in a uniform composition all over the solution. Owing to the comparatively smaller particle size, the mixture tends to be homogeneous as opposed to that of a suspension. However, a colloidal solution is simply a heterogeneous mixture, for example milk. We are not able to see colloidal particles with naked eyes as they are very small in size.

Hence, we can say that, milk is a colloid

Thus, the correct option is B.

Note:

As we know that, the metals are the elements having good electrical and heat conductivity. But some metals are soft in nature in their pure form. An alloy is a mixture composed of two or more metallic elements composed to enhance the physical nature of a pure metal.
