The process of converting a precipitate into a colloidal solution is known as:

Identify the correct molecular picture showing what happens at the critical micellar concentration $(CMC)$ of an aqueous solution of a surfactant $(\circ \text{ polar head; } \sim \text{ non-polar tail; } \bullet \text{ water})$.

When an excess of a very dilute aqueous solution of $KI$ is added to a very dilute aqueous solution of silver nitrate,the colloidal particles of silver iodide are associated with the Helmholtz double layer in the form of:

What is the cause of the Tyndall effect in a colloidal solution?

Colloidal solutions of metals like gold,silver and platinum are generally prepared by using

Among the following,the surfactant that will form micelles in aqueous solution at the lowest molar concentration at ambient conditions is
