Cellulose nitrate dispersed in ethanol is called:

Options

A. Emulsion
B. Micelle
C. Collodion
D. Hydrophilic sol

Answer

To solve the question "Cellulose nitrate dispersed in ethanol is called:", we can follow these steps:

### Step 1: Understand the Components
- Identify the components involved in the question:
- **Cellulose nitrate**: This is a type of polymer that can be used in various applications, including as a film-forming agent.
- **Ethanol**: This is an alcohol that can act as a solvent.

### Step 2: Define the Mixture
- When cellulose nitrate is dispersed in ethanol, it forms a mixture where cellulose nitrate particles are suspended in the ethanol solvent.

### Step 3: Identify the Type of Mixture
- A mixture where solid particles are dispersed in a liquid medium is known as a colloid. In this case, cellulose nitrate acts as the dispersed phase (solid), while ethanol acts as the dispersing medium (liquid).

### Step 4: Name the Colloidal System
- The specific colloidal system formed by cellulose nitrate in ethanol is commonly referred to as **Alkosol**. This term is used to describe the colloidal solution of cellulose nitrate in an alcohol medium.

### Final Answer
- Therefore, cellulose nitrate dispersed in ethanol is called **Alkosol**.
