For the coagulation of a negative sol, the species below, that has the highest flocculating power is :
Solution
For a negative sol, a positive ion is required for flocculation.
The greater the valence of the flocculating ion added, the greater is its power to cause
precipitation. This is called Hardy-Schulz law.<br><br>
So, Ba<sup>+2</sup> has highest flocculating power.
