Identify the correct decreasing order of precipitation power of flocculating ion added, from following.
Options
- AAl ³⁺> Na ⁺ Ba ²⁺
- BBa ²⁺> Al ³⁺> Na ⁺
- CAl ³⁺> Ba ²⁺> Na ⁺
- DNa ⁺> Ba ²⁺> Al ³⁺
Correct answer
C. Al ³⁺> Ba ²⁺> Na ⁺
Step-by-step solution
Higher is the valency of ion or charge of ion more will be its precipitation power. Al ³⁺> Ba ²⁺> Na ⁺
