Question

Out of KI and K2SO4 which electrolyte is better in the population of positive sol ?

Answer 1

Answer:

K2SO4

Explanation:

K2SO4 is better electrolyte then KI in the coagulation of positive sol

Answer 2

K2SO4 is better in the coagulation of positive sol than KI.

- According to Hardy SChulze's rule, greater the valency of the active ion or flocculating ion, greater will be the coagulating power of it.

- Here, as it can be clearly seen, the valency is 1 in case of KI.

- In case of K2SO4, the valency is 2.

Hence, K2SO4 is better in the coagulation of positive sol than KI.
