The flocculation values (mmol/L) of $NaCl$ , $BaCl X_{2}$ and $AlCl X_{3}$ for an $As X_{2} S X_{3}$ sol are 52, 0.69 and 0.093. Taking the coagulating power of $NaCl$ as 1 and defining coagulating power as the reciprocal of the flocculation value, find the relative coagulating power of $AlCl X_{3}$ (nearest integer).

Numerical answer type, tolerance 0.5.

Answer: 559

Coagulating power is inversely proportional to the flocculation value. Relative power of

AlCl X_{3}

= 52/0.093 = 559.1

, which is 559 to the nearest integer.
