Colloidal solution of a liquid dispersed in solid is called gel. True/False

Answer

To determine whether the statement "Colloidal solution of a liquid dispersed in solid is called gel" is true or false, we can analyze the components of the statement step by step.

### Step 1: Understand the Definition of Colloidal Solutions
A colloidal solution consists of two phases: a dispersed phase and a dispersion medium. The dispersed phase is the substance that is distributed throughout another substance.

**Hint:** Remember that in colloidal systems, the dispersed phase can be solid, liquid, or gas, while the dispersion medium can also be solid, liquid, or gas.

### Step 2: Identify the Components in the Statement
In the given statement, we have:
- Dispersed phase: Liquid
- Dispersion medium: Solid

This means we are looking at a situation where a liquid is dispersed within a solid.

**Hint:** Think about what happens when a liquid is mixed with a solid and how that relates to colloidal systems.

### Step 3: Define Gel
A gel is a specific type of colloidal system where a liquid is dispersed in a solid. In this case, the solid acts as the dispersion medium, and the liquid is the dispersed phase. Gels have a semi-solid consistency, which is characteristic of this type of colloidal solution.

**Hint:** Recall examples of gels, such as jellies or certain types of cheese, which illustrate this concept.

### Step 4: Conclusion
Since the statement accurately describes a gel as a colloidal solution of a liquid dispersed in a solid, we can conclude that the statement is true.

**Final Answer:** True
