Colloids are defined as the mixtures where the size of the particle is within the range of 2nm to 1000 nm. In these mixtures, physical boundary is seen between the dispersed phase and dispersed medium.
Tyndall effect is defined as the effect in which scattering of light takes place by the particles present in a colloid or in very fine suspension. For Example: Scattering of sunlight by clouds
Brownian motion is the movement of finely suspended colloidal particles due to collisions.
Mohs is a scale used to determine the hardness of materials
Faraday is a law which states that the mass of the substance deposited at any electrode is directly proportional to the quantity of electricity or charge passed.
<span>A colloid can be detected by using the Tyndall effect. The correct option among all the options that are given in the question is the second option. The other choices are incorrect and can be easily neglected. I hope that this is the answer that you were looking for and the answer has actually come to your desired help.</span>
You strat off with 400 grams of your substance. By day 14, half has dcayed and you only have 200 grams left. By day 28, there are 100 grams of the substance. On day 42, there are 50 grams left. Finally, on day 56, the substance has been through four half-lives and 25 grams remain.
