Flocculation value of

\mathrm{BaCl}_2

is much less than that of

\mathrm{KCl}

for sol

\mathrm{A}

and flocculation value of

\mathrm{Na}_2 \mathrm{SO}_4

is much less than that of

\mathrm{NaBr}

for sol

\mathrm{B}

. The correct statement among the following is

View answer and explanation

Correct option: B

Sol A is positively charged and Sol B is negatively charged.

Option B is correct because the flocculation value is inversely proportional to the charge on the sol. Lower flocculation value implies higher charge, hence A is positive and B is negative.
