Question

You have been given a transparent liquid that could be a solution or a colloid. What is the test you

can perform to confirm which type of mixture it is? What is the technical name for this test?

Answer 1

One way to determine whether a transparent liquid is a solution or a colloid is to use the Tyndall effect. The Tyndall effect, also known as the Tyndall scattering, is a phenomenon that occurs when a beam of light passes through a colloidal system (a mixture in which one substance is dispersed evenly throughout another). When this happens, the light is scattered by the particles in the colloidal mixture, causing the mixture to appear hazy or cloudy. In contrast, if the transparent liquid is a true solution (one in which the solute is completely dissolved in the solvent), the light will pass through it without being scattered, and the solution will appear clear.

To perform the Tyndall effect test, you would need a light source (such as a flashlight or a laser pointer) and a dark room or area. Place the transparent liquid in a clear container, and shine the light through it. If the light is scattered by the particles in the mixture, it will be visible as a bright beam or spot on the opposite side of the container. If the light passes through the mixture without being scattered, it will appear as a continuous, unbroken beam.

There are other tests that can be used to distinguish between solutions and colloids, such as the filterability test and the centrifugation test. However, the Tyndall effect test is one of the most straightforward and reliable methods for making this distinction.

Answer 2

Answer: Filterability Test

Explanation: This involves filtering the liquid through a filter paper to see if the particles pass through or are retained on the paper. If the particles pass through, the liquid is likely a solution. If the particles are retained, the liquid is likely a colloid. The technical name for this test is the separation test.
