Identify the correct decreasing order of coagulating value of the following electrolytes when each of them is separately added to $$As2S3$$ $$sol(Assume$$ all electrolytes are strong $$electrolytes)$$.

Question

Identify the correct decreasing order of coagulating value of the following electrolytes when each of them is separately added to $$As2S3$$ $$sol(Assume$$ all electrolytes are strong $$electrolytes)$$.

Infinity Learn · Accepted Answer

$$As2S3$$ is a negative sol. According to Hardy Schulze rule “A negative sol is most effectively coagulated by a cation with higher valency”.∴ coagulating power of $$Al+3$$>$$Ba+2$$>$$Na+$$ in the coagulation of $$As2S3$$ solution.Number of milli moles of electrolyte added to one litre of colloid to protect it from coagulation in two hours is called flocculating value or coagulating value.Coagulation power ∝$$1Coagulation$$ value;Thus coagulating value of $$Al+3$$

Identify the correct decreasing order of coagulating value of the following electrolytes when each of them is separately added to ${As}_{2} S_{3}$ sol(Assume all electrolytes are strong electrolytes).
