On the basis of Hardy-schulze rule explain why the coagulating power of phosphate is higher than chloride ?

Explanation

To explain why the coagulating power of phosphate is higher than that of chloride based on the Hardy-Schulze rule, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Coagulating Power**:
- Coagulating power refers to the minimum amount of an electrolyte required to cause the precipitation of a colloidal solution (sol). The lower the amount needed, the higher the coagulating power.

2. **Introducing Hardy-Schulze Rule**:
...
