Question

The experimentally measured flocculation values for a specific negative sol using $NaCl$ and $AlCl_3$ are $52$ and $0.093$ respectively. Approximately how many times greater is the coagulating power of $AlCl_3$ compared strictly to $NaCl$?

Prashant Kotian · Accepted Answer

Correct answer: C. Coagulating power is strictly inversely proportional to the flocculation value. Therefore, the ratio of the coagulating power of to is simply the inverse ratio of their values: . Rounding yields 560 times.
