Question

The flocculation value of BaCl 2 is much less than that of KCl for sol A and the flocculation value of Na 2 SO 4 is much less than that of NaBr for Sol B. The correct statement among the following is: (A) Both the sols A and B are negatively charged (B) Sol A is positively charged arid Sol B is negatively charged (C) Both the sols A and B are positively charged (D) Sol A is negatively charged and sol B is positively charged

In first case the given compounds have same anion but different cations having different charge hence they will precipitate negatively charged sol i.e. ‘A’.
In second case the given compounds have similar cation but different anion with different charge. Hence they will precipitate positively charged sol. i.e. ‘B’.

Q. The flocculation value of BaCl2​ is much less than that of KCl for sol A and the flocculation value of Na2​SO4​ is much less than that of NaBr for SolB. The correct statement among the following is:

Both the sols A and B are negatively charged

Sol A is positively charged arid Sol B is negatively charged

Both the sols A and B are positively charged

Sol A is negatively charged and sol B is positively charged
