Which of the following has maximum value of flocculating power?

Options

A. `Pb^(2+)`
B. `Pb^(4+)`
C. `Sr^(2+)`
D. `Na^(+)`

Explanation

To determine which of the given options has the maximum value of flocculating power, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Flocculation and Coagulation**:
- Flocculation refers to the process where fine particulates are agglomerated into a floc. Coagulation is similar but typically involves a larger amount of electrolyte, resulting in a more permanent precipitate.
- Both processes involve the neutralization of charges on particles to allow them to come together.
