Given below are two statements : Statement I : In the coagulation of a negative sol, the flocculating power of the three given ions is in the order - Al 3 + > Ba 2 + > Na + Statement II : In the coagulation of a positive sol, the flocculating power of the three given salts is in the order - NaCl > Na 2 SO 4 > Na 3 PO 4 In the light of the above statements, choose the most appropriate answer from the o
Options
- ABoth Statement I and Statement II are incorrect.
- BStatement I is correct but Statement II is incorrect.
- CStatement I is incorrect but Statement II is correct.
- DBoth Statement I and Statement II are correct.
Correct answer
B. Statement I is correct but Statement II is incorrect.
Step-by-step solution
The flocculating power of an ion is directly proportional to its charge present. So flocculating power of Al 3 + > Ba 2 + > Na + and similarly flocculating power of PO 4 3 - > SO 4 2 - > Cl -
