What is coagulation process ?

Explanation

### Step-by-Step Solution:

1. **Definition of Coagulation**: Coagulation is a process in which small particles suspended in a liquid clump together to form larger aggregates or masses.

2. **Role of Coagulants**: In the coagulation process, specific chemicals known as coagulants are added to the liquid (often water) to facilitate this clumping. These coagulants help to neutralize the charges on the particles, allowing them to come together.

3. **Formation of Flock**: As the particles clump together, they form larger, heavier masses known as "flock." This flock can then settle out of the liquid due to its increased size and weight.
