The most effective coagulating agent for antimony sulphide sol is
- A \(\mathrm{K}_2 \mathrm{SO}_4\)
- B \(\mathrm{NH}_4 \mathrm{Cl}\)
- C \(\mathrm{Al}_2\left(\mathrm{SO}_4\right)_3\)
- D \(\mathrm{K}_4\left(\mathrm{Fe}(\mathrm{CN})_6\right)\)
Answer & Solution
Correct Answer
(C) \(\mathrm{Al}_2\left(\mathrm{SO}_4\right)_3\)
Step-by-step Solution
Detailed explanation
According to Hardy-Scheulze rule, the coagulating power of an electrolyte will be higher for ionic components having greater charges or valencies. For coagulating a sol of a particular charge, we add particles of opposite charge. Thus, to coagulate antimony sulphide sol which is…
